Steam Most Game Hours on Steam?

Counter-Strike: Global Offensive 484 hours
Next 7 Days to Die 196 hours

The game with most hours for me would be Garry's Mod at 971 Hours right now
Second would be CS:GO at 527 hours and third would be Heroes and Generals at 378 hours

1,256 hours in Team Fortress 2 (Haven't played in a while) and then 835 hours on Garrys Mod. My two highest playtime games. Stil no better at playing them though.

I spend too much time on GO throughout multiple accounts :/

The most hours I have on a game is 5494 hours on Garry's Mod

I have around 2000+ hours on csgo across all of my accounts

I have so much playing on ArmA III in RP Life and got 3000+ hours

I got 140 hours on Shogun 2 Total War, & 120 odd hours for DOTA 2, everything else is pretty much 10-30 hours on average.

1.1k Hours on Garry's mod, And 400 on CS:GO But that's pretty much it.

I have 1,400 hours on garrys mod currently, which is my greatest amount of hours yet on any game.
