I will quote collin as this is exactly what i would say. I already put over 20 hours on sonic transformed and of course blops 2 is always fun online. I have zombie U and the atmosphere is excellent, although it has a few glitches. Assassins Creed is simply huge. The single player story is pretty damn good and there is so much to do. Not sure if you've ever played multiplayer on a creed game but it is pretty intense when you get a good group.
I've played multiplayer on creed a lot and it's awesome. The question is whether I should get it on 360 or Wii U. Still can't decide
