There are 5 games on my Steam list over 100 hours, maxing out ~300 hours: Stardew Valley, Skyrim, No Mans Sky, Don’t Starve, Cyberpunk 2077
If we include Nintendo games it probably goes up to 8: BotW, TotK, Animal Crossing New Horizons.
So at the most, I’ll spend a couple months on a game before moving on - most other games I play are either quick weekend completions, or maybe take a couple of weeks to finish. Usually when I start putting months into a game I begin to seriously question whether I’m making the best use of my time and the “what am I doing with my life” itch makes me quit games for a bit. 😅
