Probably my favorite type of game, I've played dozens of them but I'm always looking for something good I might have missed. My personal favorite for the past few years has definitely been Farthest Frontier but theres been a ton of good ones. And if anyone else is looking for recommendations let me what you like and I probably know something that fits.
RimWorld mods are great, I think I was at like a 120 mods last time I played.
I think my peak was like 300ish and then I realized how much it was slowing down my computer. Just started a Juche android colony a couple days ago.
