What game have you spent the most hours playing?

Minecraft. 12 year old me spent a lot of time with the mob talker mod

The game I played the most was Pokemon Y, not because the game was particularly good, but because that is when I REALLY got into competitive Pokemon. I think it was somewhere around 760 hours, and I have never topped that since.

Most game I've played is ArmA 3. Over 1500 hours in that game. If we count outside of steam then that would probably be World of Warcraft, which I probably have over 2000 hours in. Another game I have over 1000 hours in is CSGO.

2034 hours in gmod. my all time fav game and ive started developing addons for it now

3,000 houers in gmod lmao in one oaccount, and onther 2k in another, soo about 5/6k

spent about +120 hours playing Rust , +90 hours CSGO , since Sudden Attack isnt a Steam game but i could say i spend like +6000 hours since beta till shutdown of the game ...

Uh, I have about 2000 hours drained into garry's mod, it's pretty horrible

It's Garry's Mod for me. I have 4k hours played in this game.

skyrim, After i took an arrow in the knee there was nothing else to do. 300 hours on ps3.

probably gmod by far although this might not seem much to those 'elite gamers' but i have over 1500+ hours
