I've played a lot of this game on Steam and I always had to put up with random crashes to the point where it got unplayable. The GOG version is much more stable, I haven't experienced crashes in my time playing the game. There's still the time manipulation problem though where you can get overwhelmed very quickly at the start of the game if you keep it in 5X because the building time doesn't scale equally with the spawning time of monsters. The easy solution (and kind of an exploit) is to play early game in 0.2X since the building is much faster then spawning rates but the game gets real boring real fast, I hope this is something that's going to be fixed in the future.
