I've got a bunch of 2011 games I haven't even started in earnest. I've got others I'm into, but haven't finished. You can pretty much name a major release from last year and I've got it, but with the exception of Modern Warfare 3, I haven't finished or even started the single player content.
I was a little ways into Assassin's Creed: Revelations, but got frustrated with a mandatory rooftop race. I barely touched Deus Ex: HR or Skyrim. I've got games I haven't even opened. Don't even get me started on my DS and 3DS collection.
So which game should I play next? Should I stick with Modern Warfare 3's single player? Should I bury myself in Skyrim? Should I finish AC:R? Play Batman, Saints Row 3, something else from my pile o' games?
TL;DR: Pick the major release from last year that I should finally get around to playing.
