Most hours spent on one game?

If I added up all the hours spent on any version of Championship Manager / Football Manager, I'm sure it'll be that.

Garry's Mod - 2501 hrs
Counter-Strike: Global Offensive - 412 hrs
Team Fortress 2 - 260 hrs
PAYDAY 2 - 161 hrs
Killing Floor 2 - 150 hrs

by me a live pls.

5k hours on dota2, why not, if I like game but dislike community

minecraft around 5k hours and mw3 almost the same and arma3 around 1k

Around 2.5k hours on gmod. Then Minecraft also but idk where I can count my hours.

In my entire life if there is a game i spend more time in it then it was Hitman. I love that game so crazy that I even play this game 6hours in a day. I can't stop playing in night too. Try to knock the mission in defferent ways was so intersting for me

at this point in time my most hours are on Path of Exile with 2759hrs

About 3500 hours on Rust so far, probaby quadruple that on minecraft

By hours you mean all time or on a single sit? If it's a single sit definitely Far Cry 4. Finished that one in 14 hours nonstop

It's GMod i have spend 5k hours in the game, it's a funny game isn't it you can do many things and build many things too
