Uncharted 3, Dark Souls, Minecraft, The Witcher 2, Frozen Synapse, Portal 2, Deus Ex: Human Revolution, Skyrim, Batman: Arkham City, The Old Republic, Shogun 2, Anno 2070, Bastion, Anomaly: Warzone Earth, Rayman Origins, Skyward Sword, Dead Space 2, LA Noire, Hegemony Gold... yep, definitely a bumper crop of great games. 2012's going to have trouble keeping up.
Especially as far as memorable games go. I mean, think back to 2010 or 2009... what do you associate with those years? New Vegas, maybe? Uncharted 2? Not much else that stays fresh (at least in my memory)... but in 2011, we have at least four absolute across-the-board classics, if not seven or eight.
