Most hours spent on one game?

Over 3000 hours on CS Source, don't know the actual time since steam didn't count hours when I first started playing it. the good old days

i put over 400 hours into my old pokemon gold on the game boy advanced, but that was a very different age of gaming, haha.
After that, my biggest time-dump that *isn't* another pokemon game would be darkest dungeon, because many hours of investment are needed to ensure your team doesn't die.

got 500+ hours on Monster Hunter Iceborne. It's a fun game and the grind is very fulfilling

Probably World of Warcraft (when it was first released)... even though it wasn't that much compared to fanatic players

i think i played Destiny for more than 1000 hours now and i never got tired of it tbh.

I have ~12k hours in WoW and ~1200 hours in Rocket League.
Who needs school, right?

i spent 3400 hours on brawlhalla.
i regret it so much

The game I have the most play time in is starcraft 1. At least 5000 hours over the past 20 years playing it. I'm horrible at the regular game type, but I love playing use map settings custom maps.

1364 hours on Crusader Kings 2. Its a pretty addicting game

Used to be Rust with around 8,200h, then Five M if we can call this shit actual game but its fun...
