Oh god, I've played RimWorld and remember it as that game that made whole days and nights vanish. Had to force myself not to start it anymore as it simply killed my productivity, sleep schedule and even sense of time.
Currently, I'm still playing Divinity Original Sin and it's still fucking rad. I'm 50 hours into the game now and I feel like I'm still in the first quarter of the game. It feels like an actual progression from old-school games rather than a regression following some trend.
