Telltale's The Walking Dead: The Game - I can't really say much more that already hasn't been said. Absolutely brilliant.

Mass Effect 3 - Loved it. Got into the series late, and regret never playing 1 / 2 earlier. I played them all back to back to back in 2012 and it was p. fun.

Assassin's Creed III - I was so excited for the setting, but so let down by the rest of the game.

Call of Duty: Black Ops II - My nostalgia for Medal of Honor and Call of Duty on PC has me buying every FPS that comes our from Call of Duty. Black Ops II was probably my favorite one in quite some time.

Borderlands 2 - Played it a few times but never really felt connected to it. It's at the top of my list to try and play again once Backward Compatibility becomes more prevalent on Xbox One.

Halo 4 - Purchased it, but only ever played multiplayer. Actually starting the campaign (through Master Chief Collection) this weekend ahead of the Halo 5 release.
