Most hours spent on one game?

Team Fortress 2, I have 1,000+ hours in that game.

Counter-Strike: Global Offensive - 2000+ hours in that game

counter strike source 8000+
csgo 4000+
cs 1.6 <2000

2000 on csgo because you know its competitive and compettiive games are lit

The most i spent on one game is 4k hrs on cs:go but it will be even more

I have 3,4k in GMOD I didn't even noticed that I had so much. I played on a server that is saddly closed now for 2k.

i have 7k on dota 2 , u need to pump those number up haha

Def world of Warcraft 500+ days played:/ could of learned a damn language by now.

I have nearly 1,500 on Destiny. Not the MOST, but I think it's a pretty decent number in my opinion.

The game I have like non stopped played for so long is Reign of kings I have around about 10k hours I just spend all day playing it and never get bored!
