Probably Dragon Age 2. I beat Dragon Age Origins more times than any other game, including the DLC. It stunned me how I fell in love with that fukkin game so hard. I thought 2 was gonna be more of the same piffery, but it was so wack and dumbed down. And the whole game taking place in essentially one city? Goddamn, they fukked up. Luckily Inquisition looks like its gonna be CRACK whenever it drops. Although that'll be a while, I can wait.
Modern Warfare 3 also. I thought IW was about to bless us again, because MW2 was my shyt. Not as much as MW1, but I still put massive hours into that shyt. They dropped the ball tho IMO and thats when I knew they were finished.
ME3, I would throw up there for the ending, because I dislike it almost as much as most people, but the action leading up to it was pretty dope. I just wish they made the last fight with ol assassin dude better.
