Modern Warfare 3 and Gears of War 3 are my bread and butter on here.
Rarely use the damn thing. Mostly used for Blu-Rays.
SKYRIM with the occasional CS:S or TF2 every once in a blue moon, as well as CoD4/WaW.
Battlefield 3, the only thing Origin will ever be used for.
As you can see, I like to change my name around quite a bit, lol.
