Zalathar: Best of 2010
I wouldn't go so far as to say that Bayonetta is better than every other game on this list, but it gets bonus points for being my most unexpected favourite of the year.
I had a real blast playing Reach for about a month, after which the Australian player population made it impossible to find a decent game of Invasion.
This should probably be higher, but since I haven't finished playing Cataclysm I don't feel qualified to rank it against single-player games I have finished.
I didn't actually *play* StarCraft II, but it gets an honourable mention for the sheer amount of time I spent watching GSL matches and Husky/HD casts.
