I have phases. I was in a Fallout 3 phase for about 9 months before I got Dragon Age, and now that's all I play. I buy new games but I can only concentrate on one at a time, and I'm such a completionist (totally a word!) I have to play the shit out of the one I'm focusing on. I have Arkham Asylum and Mass Effect 2 sitting around waiting for me, but until I finish all 6 of Dragon Age's origin stories and Awakenings comes out I won't get to them. If I want a break I'll play Fallout 3, ME1, Portal, or Fable 2, but I won't crack the package on a new game until I've finished my current game.
Ha! This post makes me sound like such a freak - OCD much?
