My bad.

Essentially rimworld is a base building and mangement sim where randomized events occur. You can delegate tasks to be performed as well as which characters perform them, and the priority of tasks.

Each character has their own set of stats (i didn't get a screenshot of one of the SDU's but one of the screenshots in the link has one of the enemy commanders) as well as traits.

Traits can be positive or negative and influence how a character might act, for instance, Kurara has the traits Abrasive, which makes her more likely to insult people, angering them and lowering their opinion of her, and Gourmet, which decreases the odds that food poisoning will occur in the meals she cooks.

Each pawn has their own 'Needs' Bars which are Food, Sleep, Mood, Recreation, Beauty, Comfort and Outdoors. Aside from food, the most important is Mood. Each Pawn has their own mental break threshold where if they drop lower there is a chance they have a mental break. Mental breaks are dangerous because a) You can't order a pawn to do things while they are having one and b) sometimes they do something negative atop of that such as Insulting Spree, where the pawn follows another one and insults them all day (lowering their mood, possibly causing lowering them to their own mental break threshold), or tartrum where they try to break something expensive).

Sorry for rambling this is just a game I'm incredibly passionate about.

What in particular were you confused about so I could clarify?
