Steam Most Game Hours on Steam?

Star Trek Online
385 hrs on record

i have played that game so much it seems. but it never seems to be that much when i started.

996 Hours in Rust (Probably over 1500 if you also count cracked) I should probably find a different game to play :/

I believe everybody saying his most played steam game is gmod since many players of that game came on that site only for gmod leaks :D Mine is CS:GO w/ about 550 hours.

CSGO, yes i'm that guy

Rocket League, nearly 1700 Hours!

Spend fucking 1244 hours on Garry's Mod...

1194 for Dota2, well i think garry mods look cool i would give a try and spend more hours to that game.

would someone love stream me ?

Oh, I have 998h of Garry's Mod (Almost 1k )
Second game, Team Fortress 2 (133h)
Third, CSGO (85h)
