Okay ill start, my most favorite games of the last decade are:
Crysis 2 & 3
COD Modern Warfare 3 & 4
I actually love the Crysis franchise more than all other games that I have played in my whole life, I love the environment, story, actions, character, graphics, and everything about the game. Still hoping that they will make Crysis 4 and will be jaw-dropping for the following years, (aah old times).
