The AI Storyteller creates events like pirate raids, resource drops, or animal attacks. Storytellers will never entirely disallow events because of population. Their choices will affect the story of your colony.
Gameplay 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.
Choosing an AI will have a great influence on the narrative that is formed as you play. Difficulty is selected separately from the Storyteller but both are changeable mid-game.
Current AI Storytellers
Cassandra Classic is the default storyteller, whose main characteristic is to throw challenges starting from easy, and progressively increasing to difficult level.
desiredPopulationMin = 4 desiredPopulationMax = 13 desiredPopulationCritical = 18 threatCycleLength = 9.2 minDaysBetweenThreatBigs = 1.9 classic_RandomEventMTBDays = 1.00 classic_ThreatBigMTBDays = 3.75 classic_ThreatSmallMTBDays = 1.25
Phoebe Chillax, is a storyteller whose main characteristic is the long break between challenges, leaving the player with enough time to rest and recover after an event, and live without much to worry about. This gives new players a more relaxed experience to get familiar with the game.
When playing with Phoebe, in the beginning its always likely to gain one or two more colonists, typically a wanderer. A trade caravan or two shall also arrive before completing a full season (15 days).
desiredPopulationMin = 4 desiredPopulationMax = 13 desiredPopulationCritical = 18 threatCycleLength = 17 minDaysBetweenThreatBigs = 12.5 classic_RandomEventMTBDays = 1.00 classic_ThreatBigMTBDays = 8 classic_ThreatSmallMTBDays = 1.25
Randy Random, is a wild storyteller whose main characteristic is triggering challenges at any time of any difficulty, to the extent of launching several dangerous threats all at the same time or consecutively.
desiredPopulationMin = 4 desiredPopulationMax = 13 desiredPopulationCritical = 50 AverageIncidentsPerDay = 1.45 GeneralWeight = 0.79 ThreatSmallWeight = 0.0950 LargeThreatWeight = 0.095 MaxThreatBigIntervalDays = 13
When the storyteller sends threats after you, they will set percentage as large as in Intense mode (the default difficulty).
|Name||Threat scale||Colonist mood bonus||Base sell price multiplier||Crop yield multiplier||Disease interval multiplier||Enemy reproduction rate factor|
Permadeath mode is an option, off by default, when selecting difficulty.
In permadeath mode, you only get one save file and can only save when quitting the game. You cannot reload the game to fix mistakes, and only when the 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.
