++++1 for Rimworld. The first time I really committed to learning to play that game, I lost almost 100 hours in ~3 weeks (which is a ton for me, since I have kids and a job… I lost a lot of sleep). The best part of Rimworld, is if there’s a vanilla mechanic you don’t like or wish was fleshed out more, there’s a 98% chance someone has made a mod for it.

But yeah, it isn’t for the faint of heart. It definitely has a learning curve and it isn’t super easy to just pick up and play for small amounts here and there. It’s a game that you really need at least 1-2 hours per session.

I’d recommend watching a quick start tutorial video before you start playing, as that’ll also give you an idea on whether or not you’ll like it.
