I didn't particulary find RimWorld to be very fun, but I did end up enjoying Oxygen Not Included, which is a side-scrolling 2d colony management sim that's a bit less serious and way more quirky.
Its just feels like instead of playing the game I must combat it.
Much more annoying are the suits (and now, gas masks). If you are not careful with settings they will drop them elsewhere, or will enter the perfectly breathable base with suits still on.
