Great that most of these games are on Steam. I played BF3 for a while but haven't reinstalled it as it didn't really capture my interest, and I HATE origin with such a huge vengeance. Awful, torrid piece of flakey rubbish. And yes, I remember the early days of steam...
I guess I'll have to reinstall origin to play dead space 3, but I'll save that for when I've got through all the other games (no need for BF3 as I already have it, and... 'The Sims 3'? Really?).
