I'm pretty new to the game (sub 100 hours) and have found a few mods that make it more suitable to my taste. My favourite so far is Research Reinvented, it makes the research system a bit more active than just having one pawn sit at the research table for days on end.

What about you guys? If you could only take one mod to the rimworld, which one would you take? Or is there a small mod that just adds one or two nice things you like? Feel free to discuss your favourites in the comments!
