I was on the fence for a long time about Rimworld. There's other games in this formula, stuff like Dwarf Fortress and Prison Architect come to mind-I waited until a steam sale to pick this up and kind of wish I'd played it sooner.

Rimworld is a spectacular kind of Sim, the one where you sit and fiend and tell yourself "one more hour" and suddenly it's six AM and your eyes hurt. Trying to keep your pawns alive is a daunting task and the fact that they can have belligerent little personalities makes it both charming and frustrating in turns. (never accept a Pyromaniac pawn into your colony. Never. That way lies agony)

The skill trees, the leveling-up of your characters in your colony, the way you interact with outside travelers and hazards, all make for addictive gameplay. The music is fantastic, but I wish there was more of it. The ability to add mods ensures you have plenty to do and tweak, and the fact that you can set the obstacles into any challenge level you want can make for an extremely chill experience. Or not. That's up to you!

I only wish the game was a little prettier as far as the graphics style is concerned, with your people being little Weebles and everything else being just as simplistic.. It's look is probably not for everyone, but if you don't judge a game by its cover, you'll find yourself satisfied by a game that has you spinning more and more plates until the inevitable and hilarious catastrophes that will befall your colony.

Also you can make drugs and eat people.
