AI Storytellers

Rimworld's AI Storyteller

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. Which AI you choose is the first decision you make in Rimworld, and will have a great influence on the narrative that is formed while you play. Some are easier or harder than others, while others may be completely unpredictable!

Current AI Storytellers

The storytellers that currently exist in the game are as follows.

Cassandra Classic

Cassandra Classic is your go-to AI for a standard Rimworld experience. She will give you a fair game experience that begins with small challenges that amp up over time to intense events that can only be survived by smart planning and perhaps a little luck.

Kassandra

Build(???) added a secondary version of Cassandra called Kassandra which runs on the same algorithm but with a slightly more challenging difficulty curve.

Phoebe Friendly

This AI is best for a sandbox experience in which you can grow your colony without major interference. Minor issues will still arise, but nothing that will seriously impede or end your game. This AI is great for learning the game or just enjoying a peaceful, creative Rimworld experience.

Randy Random

Randy is the wildcard AI. Any AI event could be triggered at any time with Randy. You may encounter insanely good trade deals, or you may find yourself faced with a raid during a storm while there is an eclipse as your power generator explodes, and you military members go insane. For those looking to ultimately lose to chaos among their attempts at order a la Dwarf Fortress, Randy Random may be the AI Storyteller for you.

Future AI Storytellers

While no other particular AIs are confirmed, there are plans for other AIs such as AI focused on raising population, creating seasonal events, creating a lack of food, and other ideas suggested by the community. It is not confirmed, but it also may be possible that AIs will be somewhat configurable in the future.
