1000-2000 hours in several games. It’s a mix of several reasons:
Some games are more replayable than others. My high-playtime games tend to be roguelikes, played over multiple years
The more you play something, the more of a comfort game it gets. It becomes easier to just play it mindlessly if you just want to turn off your brain
Some games have inconvenient save systems, intentional or otherwise (especially true for roguelikes). This incentivizes you to just leave the game running overnight instead of saving and quitting. Just once and you’re looking at ~20 hours added to your playtime. Rinse and repeat for multiple nights
