exactly perfectly rightly civilizedly cooly
: 2911 On Garry's Mod! :

Conter Strike Global Offensive - 1954h, but last time i don't play to much in games, no it's time for tv series for me :D

I have 419 hrs on record for Team Fortress 2, but i have 686 hrs on record for Substance Painter lol.

I have Counter-Strike: Global Offensive as my main game at the moment. Got over 2.500 hours, love the game. It's amazing when you got good teammates and people who don't rage when you lose/ make mistakes. Again, great game.
Sold over 10 accounts that I reached LEM+ with.

I play Rocket League primarily on Steam but I have easily over 1k hours on Black Desert Online. So much AFK fishing and processing to be done.

Garry's Mod with 796 hours. Second one is rainbow six siege with 591 hours

War thunder at 303 hours and Skyrim close second with 267 hours.

Currently at 4500 Hours on Arma 2 operation arrowhead, mostly from AFK lol.

I have Garry's Mod sitting at 1765 hours and counting.
