2011 for me, so many good and big games that year, Skyrim, LA Noire, Deus Ex Human Revolution, Witcher 2, Arkham City, Portal 2, Forza Motorsport 4, Gears of War 3, Zelda Skyward Sword, Dead Space 2, Yakuza 4, Star Wars The Old Republic, Rage, Crysis 2, Resistance 3, Dark Souls, Battlefield 3, CoD Modern Warfare 3, Halo Combat Evolved Anniversary, Assassin's Creed Revelations, Saints Row The Third, Minecraft.
No other gaming year has been even close to that packed with big games. Certainly not for me, there are more 2011 games on my top 50 games of all-time list than any other year.
