This is probably my favorite game, it’s going through a rough patch right now because development had halted for about a year and was then sold to another company last year who are still in the process of transferring everything over. I’m hoping for new development within another year because it’s an awesome game, but it’s been stagnant for a long time. It’s not on sale, but they’ve discussed a lower price for it openly after they get things rolling. We’ll see.
I cannot think of a game that has better value for money than Factorio.
Rimworld. It's the only other one I can think of that people play for insane hours, it's still my most played game and I've barely touched it in a long while, I think I have 1400ish, my boyfriend has over 3.5k hours
