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.
ONI made me think I needed a chemistry and engineering degree to play the game without looking at tutorials to do basically everything.
It’s one of those games that overwhelms you with complexity right off the bat but the mechanics aren’t actually that bad when you get a feel for them. It’s nowhere near as hard as something like dwarf fortress.
