Steam Most Game Hours on Steam?

2088 hours in CS:GO. Shame I had few accounts in WoW, so I can't check how many hours i spent there overall. I'd say ~10k, but thats not on steam so It doesn't count :D

CSGO with nearly 900 Hours and Rust/Arma3/Rocket League with 300 Hours

I have 1800 hours on GMOD and TF2, + 1300 on cs. Not a waste of time.

I've got 1074 hours on TF2, although I don't play it much anymore.

I have over a thousand hours on Garry's mod and I have wasted my life.

actually battleborn with 200 hours, i really liked the game before it was dead ^^

I have Counter Strike Global Offensive 1400+Hours.....

I'm totally not addicted... Garry's Mod = 1508 hours :D

I have 2,500 hours on Garry's Mod.. I have no life..
