I assume that they only started counting time past a certain version of the Steam API, so older play throughs don't show up as apart of that time. Expansions and DLC would show up with the original go, or so I'd hope.
Deus Ex: Human Revolution's The Missing Link counts its playtime separately from the main game for me. I don't have many multiplayer online steam games. Kinda brutal. I have Magicka, but outside of the magic.system and the coop the game fails
Hey guys my Gamer Tag for xbox live is: RathDragon. I have a lot of games but I'll just list the ones I play online with.
COD MW 3, COD Black Ops (No Zombies), Saints Row 2 & 3, Fable 2 & 3, Homefront, and Mass Effect 3. If u play any of these games please add me, I'm a pretty easy gamer to get along with.
