Ludeon's own pages say RimWorld is a story generator that works by controlling random events, each one 'a card dealt into your story' by the AI storyteller; the designer's 2013 devlog names three storytellers whose policies are a pre-defined tension curve, pure randomness, and 'nothing bad happens'. The numeric mechanism (what inputs, what curve, what thresholds) is not given in any first-person text obtained; only the community wiki describes inputs such as colony wealth and time since the last major event, and a push/breathe cycle for Cassandra. No evaluation of the storytellers by the developer was found.
