The '''AI storyteller''' is the main mechanism used to determine game difficulty and play style. There are currently three presets for narrative settings. Each preset features different raid frequencies and an eponymous cartoon mascot. The player must choose either '''Cassandra Classic, Phoebe Chillax, or Randy Random''' to act as their "unseeable God." They will periodically

The gameplay of '''RimWorld''' is driven by AI (Artificial Intelligence) Storytellers. The AI Storyteller that you choose will make decisions about what events it wants you to encounter and when, based on the situation you are currently in and on the biases of that particular AI.

create [[events]] for your colony, including pirate raids, resource drops, or [[manhunter]] animal packs.
 +
The AI Storyteller does not have an in-game body, location, or manifestation; it is just a name given to describe game settings.

+
Your choice of storyteller sets the tone for your colony - a more benevolent storyteller like Phoebe will send trade caravans or helpful travelers after hitting your colony hard with a tough raid.
−
Choosing an AI is the first decision you make in '''RimWorld''', and will have a great influence on the narrative that is formed as you play. Some are easier or harder than others, while others may be completely unpredictable!</translate>
+
 
 +
The frequency and type of storyteller events are based on a number of factors. Colony wealth, building wealth, colonists count, animal count, if a colonist has died or been severely wounded recently, and how long it has been since the last major event are all considered before a storyteller event occurs.
 +
 
 +
The difficulty is adjusted separately from the storyteller, however, some storytellers are less merciful than others. Both difficulty and storyteller are changeable mid-game from the Settings Menu, with no downside or penalty.

:''Main: [[Chill Callie Classic]]''

There are 6 default difficulties:
 +
{| class="wikitable" style="width=600"
 +
|-
 +
! Difficulty !! In-game description
 +
|- id="Peaceful"
 +
! Peaceful
 +
| Build a community in a sandbox environment. Major direct threats are disabled, but challenges like disease, mental breaks, and mad animals can still occur.
 +
Recommended for:
 +
* Players who want to learn the game mechanics with minimal pressure.
 +
* Players who just want to build.
 +
* Players who just want to relax.
 +
|- id="Community builder"
 +
! Community builder
 +
| Build a community with a taste of danger. Threats appear, but they're weakened.
 +
Recommended for:
 +
* Players who are new to this kind of game.
 +
* Players who want to build a perfect colony.
 +
* Players who want to relax.
 +
|- id="Adventure story"
 +
! Adventure story
 +
| There's room to grow and thrive, but it's still a dangerous planet.
 +
Recommended for:
 +
* Experienced strategy gamers on their first game of RimWorld.
 +
* Experienced RimWorld players who want some breathing room to pursue funny or weird goals.
 +
|- id="Strive to survive"
 +
! Strive to survive
 +
| Strive to survive on a rough, tough planet. There will be triumph and tragedy.
 +
Recommended for:
 +
* Experienced players who want a rough story requiring skill to survive.
 +
|- id="Blood and dust"
 +
! Blood and dust
 +
| Face brutal survival challenges. Even if you play well, people will die. You will need to anticipate threats before they arrive, and seek out every advantage.
 +
Recommended for:
 +
* Experienced players who want to struggle to survive.
 +
|- id="Losing is fun"
 +
! Losing is fun
 +
| This setting is designed to be unfair. Huge threats will crash upon you without mercy until your colony dies. Only choose this setting if you are happy with the drama of struggling and dying.
 +
Recommended for:
 +
* Experienced players who want to face a brutal, unfair challenge where even great skill may not prevent death.
 +
* Lovers of tragedy.
 +
* Digital masochists.
 +

 +
 
 +
Each difficulty works by changing the values of each setting, displayed down below. Using the Custom difficulty will allow you to change each setting yourself. The default values are based on the "Strive to survive" difficulty level, where most values are at 1.0, or 100%. When creating a custom difficulty, you can use the "Set to Standard Playstyle" button to change the values to one of the 6 default difficulties.
 +
 
 +
=== Commitment mode===
 +
When creating a game, the player must choose between "Commitment" and "Reload anytime" mode. Unlike storyteller and difficulty, '''this cannot be changed after game creation'''. If desired, you can disable (or enable) commitment mode by [[Permadeath save conversion guide|editing the save file]].
 +
 
 +
With reload anytime, you can save and reload the game as you wish. Good if you're still learning the game, if you intend to self-enforce commitment mode, or if you want to have a more relaxed experience. RimWorld is a single player game - nobody will judge you for playing with saves.
 +
 
 +
In commitment mode, you only get one save file and can only save when quitting the game. You cannot reload the game to fix mistakes. When the entire colony dies, but ''only'' when the entire colony dies, [[Endings#Colony End|that's it]]. This is the way RimWorld was meant to be played with every dramatic turn - whether tragic or hopeful - played out to full impact. (Note: this can be dangerous if you use lots of mods - if something soft-locks, you cannot go back to an earlier save to avoid the situation!)

Wealth-independent mode removes the wealth factor and replaces it with a fixed progress curve based on time. The time is counted from the founding of each colony. This is only recommended for those looking for a strict skill challenge. In wealth-independent mode, it may be nearly impossible to recover from serious losses unless you found a new settlement.

=== New colonist events ===
 +
The formula that calculates the odds of random events that add new colonists has changed in 1.0. It factors in how long a player has been at the location for which the event is generated, and the current population of that colony, including pawns who are traveling on the world map. These events include "[[Events#Refugee Chased at .28Settlement.29|refugee chased]]", "[[Events#Transport pod crash|transport pod crash]]", "[[Events#Wanderer joins|wanderer joins]]" and "[[Events#Wild .28wo.29man wanders in|wild (human) wanders in]]".

The following code examples and analysis were provided by user Bar0th on Steam, who gave permission for their inclusion here. <!-- This is the URL of the Steam forum thread: steamcommunity.com/app/294100/discussions/0/1651043320656662118/ --> To summarize these findings: There is a new variable, "PopulationIntent," which replaces the old variables "desiredPopulationMin," "desiredPopulationMax" and "desiredPopulationCritical." It controls the odds of colonist-adding incidents happening on a particular map. The odds based on the time at location decrease until the 10th day, and the odds based on population decrease until the 20th colonist. (For purposes of this formula, prisoners count as half a colonist.) Once both variables have decreased to their long-term minimum, the odds remain stable. Randy's minimum chance is .08%, while for Cassandra and Phoebe the minimum chance is .02%, so Randy is still the best option for players who wish to reach a large colony size.

  ''Other: 0.24% (0.4 x Max(-0.4 + 1.0, 0.05) = 0.4 x 0.6)''<br>

  - They are the same, because of the high PopulationIntent.
 +
 
 +
''Day >= 10, 20+ Population (PopulationIntent = -1.0):''<br>
 +
 
 +
  ''Randy: 0.08% (0.4 x Max(-0.4 + -1.0, 0.2) = 0.4 x 0.2)''<br>
 +
  ''Other: 0.02% (0.4 x Max(-0.4 + -1.0, 0.05) = 0.4 x 0.05)''<br>
 +
  - Here, the low PopulationIntent allows Randy's higher minIncChancePopulationIntentFactor to take effect.
 +
 
 +
So, there doesn't appear to be a hard cap on any of the storytellers anymore. However, some events can become much rarer at high populations (0.02% chance of a wanderer join, 0.08% if using Randy @ 20+ population). Also, for purposes of population calculation, it searches the entire map for pawns of that colony (ie: includes caravans, etc), and it also includes prisoners of that colony (each prisoner counts as half a colonist).
 +
 
 +
The multiple colony trick works, because it doesn't check all pawns in the map for all colonies, only the one it is currently determining the event for.
 +
 
 +
Also, you can check the table for the PopulationIntent from the "debug logging menu" while in dev mode. Search for the population, and you can bring up the table. You'll notice that after 10 days (at the top), and populations > 20 (at the left) the numbers remain the same. That's because of the curves in Storytellers.xml:

Revision as of 14:42, 12 November 2024

Basics Menus Game Creation Gameplay Pawns Plants Resources Gear Mods
Game Creation Scenario system AI Storytellers World Generation Biomes
AI Storytellers Cassandra Classic Phoebe Chillax Randy Random

The AI storyteller is the main mechanism used to determine game difficulty and play style. There are currently three presets for narrative settings. Each preset features different raid frequencies and an eponymous cartoon mascot. The player must choose either Cassandra Classic, Phoebe Chillax, or Randy Random to act as their "unseeable God." They will periodically create events for your colony, including pirate raids, resource drops, or manhunter animal packs. The AI Storyteller does not have an in-game body, location, or manifestation; it is just a name given to describe game settings.

Your choice of storyteller sets the tone for your colony - a more benevolent storyteller like Phoebe will send trade caravans or helpful travelers after hitting your colony hard with a tough raid.

The frequency and type of storyteller events are based on a number of factors. Colony wealth, building wealth, colonists count, animal count, if a colonist has died or been severely wounded recently, and how long it has been since the last major event are all considered before a storyteller event occurs.

The difficulty is adjusted separately from the storyteller, however, some storytellers are less merciful than others. Both difficulty and storyteller are changeable mid-game from the Settings Menu, with no downside or penalty.

Current AI storytellers

Cassandra.png

Cassandra Classic

Cassandra creates story events on a classic increasing curve of challenge and tension.
She'll push you with dangerous events, then give breathing room, then come back to push once more.

Phoebe.png

Phoebe Chillax

Phoebe gives lots of time between disasters to build your colony.
But beware - at high difficulties, she'll hit as hard as anyone.

Randy.png

Randy Random

Randy doesn't follow rules.
He'll generate random events, and he doesn't care if they make a story of triumph or utter hopelessness. It's all drama to him.

Warning: Since Randy is truly random, he will sometimes send extremely difficult or unfair groups of events at you.
It makes for high drama - and unavoidable sacrifices.

Difficulties

There are 6 default difficulties:

Difficulty In-game description
Peaceful Build a community in a sandbox environment. Major direct threats are disabled, but challenges like disease, mental breaks, and mad animals can still occur.

Recommended for:

  • Players who want to learn the game mechanics with minimal pressure.
  • Players who just want to build.
  • Players who just want to relax.
Community builder Build a community with a taste of danger. Threats appear, but they're weakened.

Recommended for:

  • Players who are new to this kind of game.
  • Players who want to build a perfect colony.
  • Players who want to relax.
Adventure story There's room to grow and thrive, but it's still a dangerous planet.

Recommended for:

  • Experienced strategy gamers on their first game of RimWorld.
  • Experienced RimWorld players who want some breathing room to pursue funny or weird goals.
Strive to survive Strive to survive on a rough, tough planet. There will be triumph and tragedy.

Recommended for:

  • Experienced players who want a rough story requiring skill to survive.
Blood and dust Face brutal survival challenges. Even if you play well, people will die. You will need to anticipate threats before they arrive, and seek out every advantage.

Recommended for:

  • Experienced players who want to struggle to survive.
Losing is fun This setting is designed to be unfair. Huge threats will crash upon you without mercy until your colony dies. Only choose this setting if you are happy with the drama of struggling and dying.

Recommended for:

  • Experienced players who want to face a brutal, unfair challenge where even great skill may not prevent death.
  • Lovers of tragedy.
  • Digital masochists.

Each difficulty works by changing the values of each setting, displayed down below. Using the Custom difficulty will allow you to change each setting yourself. The default values are based on the "Strive to survive" difficulty level, where most values are at 1.0, or 100%. When creating a custom difficulty, you can use the "Set to Standard Playstyle" button to change the values to one of the 6 default difficulties.

Commitment mode

When creating a game, the player must choose between "Commitment" and "Reload anytime" mode. Unlike storyteller and difficulty, this cannot be changed after game creation. If desired, you can disable (or enable) commitment mode by editing the save file.

With reload anytime, you can save and reload the game as you wish. Good if you're still learning the game, if you intend to self-enforce commitment mode, or if you want to have a more relaxed experience. RimWorld is a single player game - nobody will judge you for playing with saves.

In commitment mode, you only get one save file and can only save when quitting the game. You cannot reload the game to fix mistakes. When the entire colony dies, but only when the entire colony dies, that's it. This is the way RimWorld was meant to be played with every dramatic turn - whether tragic or hopeful - played out to full impact. (Note: this can be dangerous if you use lots of mods - if something soft-locks, you cannot go back to an earlier save to avoid the situation!)

Classic mortars Mortars will not require reinforced barrels to construct or reload, and are balanced for this ease of access.

With "Classic Mortars", mortars are as they were before 1.3. Namely:

  • The barrel need not be changed every 20 shots.
  • Reinforced barrels are removed from the recipe and game.
  • Forced miss radius increased from 9 to 13.
  • Steel cost of all mortar shells increased by 10.

Note that the Mortar Miss Radius Multiplier still applies with this setting applied.

Adaptation

Options Description Value options Peaceful Community builder Adventure story Strive to survive Blood and dust Losing is fun

Wealth-independent progress mode Play in a wealth-independent progress mode. In normal mode, the storyteller scales threats according to colonist count, player wealth, and a variety of other factors. Wealth-independent mode removes the wealth factor and replaces it with a fixed progress curve based on time. The time is counted from the founding of each colony. This is only recommended for those looking for a strict skill challenge. In wealth-independent mode, it may be nearly impossible to recover from serious losses unless you found a new settlement. It's also possible to get too far ahead of the curve and find the game too easy. Toggle Ex.png
Years until maximum threat The number of game years until the wealth-independent mode reaches its maximum threat level. Note that the storyteller will still scale threats according to colonist count and a variety of other factors. 1 - 20 12

The formula that calculates the odds of random events that add new colonists has changed in 1.0. It factors in how long a player has been at the location for which the event is generated, and the current population of that colony, including pawns who are traveling on the world map. These events include "refugee chased", "transport pod crash", "wanderer joins" and "wild (human) wanders in".

The following code examples and analysis were provided by user Bar0th on Steam, who gave permission for their inclusion here. To summarize these findings: There is a new variable, "PopulationIntent," which replaces the old variables "desiredPopulationMin," "desiredPopulationMax" and "desiredPopulationCritical." It controls the odds of colonist-adding incidents happening on a particular map. The odds based on the time at location decrease until the 10th day, and the odds based on population decrease until the 20th colonist. (For purposes of this formula, prisoners count as half a colonist.) Once both variables have decreased to their long-term minimum, the odds remain stable. Randy's minimum chance is .08%, while for Cassandra and Phoebe the minimum chance is .02%, so Randy is still the best option for players who wish to reach a large colony size.

PopulationIntent (from StorytellerDef):
 populationIntentFactorFromPopCurve x populationIntentFactorFromPopAdaptDaysCurve

minIncChancePopulationIntentFactor
 Default = 0.05 (from C#)
Randy = 0.20 (from StorytellerDef)

IncidentChanceFactor_PopulationIntent (from C#):
 None = 1
IncreaseHard = Max(0.4 + PopulationIntent, minIncChancePopulationIntentFactor)
IncreaseMedium = Max(PopulationIntent, minIncChancePopulationIntentFactor)
IncreaseEasy = Max(-0.4 + PopulationIntent, minIncChancePopulationIntentFactor)

IncidentChanceFinal (from C#):
 baseChance (from IncidentDef) x IncidentChanceFactor_PopulationIntent

Example Event: Wanderer Join (baseChance = 0.4, populationEffect = IncreaseEasy)

Day >= 10, 5 Population (PopulationIntent = 1.0)


Randy: 0.24% (0.4 x Max(-0.4 + 1.0, 0.2) = 0.4 x 0.6)
Other: 0.24% (0.4 x Max(-0.4 + 1.0, 0.05) = 0.4 x 0.6)
- They are the same, because of the high PopulationIntent.

Day >= 10, 20+ Population (PopulationIntent = -1.0):

Randy: 0.08% (0.4 x Max(-0.4 + -1.0, 0.2) = 0.4 x 0.2)
Other: 0.02% (0.4 x Max(-0.4 + -1.0, 0.05) = 0.4 x 0.05)
- Here, the low PopulationIntent allows Randy's higher minIncChancePopulationIntentFactor to take effect.

So, there doesn't appear to be a hard cap on any of the storytellers anymore. However, some events can become much rarer at high populations (0.02% chance of a wanderer join, 0.08% if using Randy @ 20+ population). Also, for purposes of population calculation, it searches the entire map for pawns of that colony (ie: includes caravans, etc), and it also includes prisoners of that colony (each prisoner counts as half a colonist).

The multiple colony trick works, because it doesn't check all pawns in the map for all colonies, only the one it is currently determining the event for.

Also, you can check the table for the PopulationIntent from the "debug logging menu" while in dev mode. Search for the population, and you can bring up the table. You'll notice that after 10 days (at the top), and populations > 20 (at the left) the numbers remain the same. That's because of the curves in Storytellers.xml:

<populationIntentFactorFromPopCurve>
<points>

  • 0, 8.0


  • 1, 2.0


  • 5, 1.0


  • 9, 0.4


  • 12, 0.0


  • 20,-1.0


    • </points>
    </populationIntentFactorFromPopCurve>

    <populationIntentFactorFromPopAdaptDaysCurve>
    <points>

  • ( 0, 0)


  • (10, 1.00)


    • </points>
    </populationIntentFactorFromPopAdaptDaysCurve>

    Further investigation and updates are needed.

    Trivia

    • The "Losing is fun" difficulty is a reference to the game Dwarf Fortress, which also happens to be that game's tagline. More specifically, it refers to Dwarf Fortress lacking a definite ending, as the game will end with the player losing no matter how skilled they are.

    Version history

    • 0.0.254B - Added Chill Callie Classic storyteller. Rebalanced Cassandra’s raiders to not send advanced enemies too early, and to pace them a bit slower.
    • 00.1.334 - Kassandra renamed to Cleopatra.
    • 0.4.460 - Storytellers now focus on wealth and let you recover from serious damage.
    • 0.11.877 - Storytellers no longer entirely disallow events because of population. Randy’s event chances are affected by population (somewhat). Re-tuned storyteller population intent based on new output tables for smoother population gain with higher maximum and better recovery at small populations
    • 0.13.1135 - Permadeath mode added - One save file, save on quit or autosave only.
    • The names of the difficulty levels were changed from 1.0 to:
      • Peaceful
      • Builder
      • Medium
      • Rough
      • Savage
      • Merciless
    • 0.14.1236 - Fix: Storyteller incorrectly adjusts trader frequency in relation to ally count.
    • 0.14.1238 - Phoebe’s random incidents density reduced. Previously the same as Cassandra’s, which conflicted with Phoebe supposedly giving more breathing space between events.
    • 0.14.1241 - Reduced event density on Randy Random from 1.5x that of Cassandra to about the same as Cassandra. The combination and distribution of events is still very different from Cassandra. Toxic fallout, flashstorm and volcanic winter are now disabled in Free Play difficulty.
    • 1.1.2647 - they have changed again to the following:
      • Peaceful
      • Community builder
      • Adventure story
      • Strive to survive
      • The price of survival is blood
      • Losing is fun
    • 1.1.2654 - "The price of survival is blood" was changed to Blood and Dust.
    • 1.2.2719 - Custom playstyle system added. You can now select a new custom playstyle setting. This opens up a new menu that allows you to customize a large number of different settings exactly as you prefer.
    • 1.2.2753 - Rename "fixed wealth" mode to "wealth-independent" mode, and give the player a slider to control how many years until this mode delivers its maximum threat level.
    • 1.3.3200 - Turret ammo cost is no longer factored by difficulty.
    • 1.4.3555 - Renamed "child raiders" storyteller setting to "child enemies" to be more accurate. Allow modifying the “child aging rate” and “babies are healthy” storyteller settings even if children are disabled, in case there are already children in the game. Fix: Wastepack cocoon infestation storyteller setting appearing in the wrong spot.
