Great social life, right ?
When you buy Garry's Mod, you either play for 2 hours or for 2000 hours.
And btw I still have no idea how I got so many hours on Half-Life 2 and Geometry dash.

Probably APB, for 1200 hours.
The game is pretty bugged and sometimes Steam recognizes it as opened even if it's not, so I'd say around 1000 hours to be correct.

Not the game I played the most though, I haven't touched it for ages.
