Ghost sucks, but to call it the WOAT is laughable. In terms of movement and hit accuracy, it's probably the best there is. You can't give WOAT to a game that is the best in such important departments. MW3 is definitely the WOAT fucking game, it's awful. The maps were terrible, the guns were so unbalanced, the game just felt completely horrible to play in every single possible way (Solidus will disagree, but I am right).
MW2 had great maps but was still pretty awful. CoD 4 is my 2nd favourite CoD of all time. Black Ops 2 was hands down the best CoD that has ever been made (and it's not even close btw). Black Ops wasn't great but it wasn't terrible either. WoW I personally hated, but I was a noob when I played it, I can see why people like it. Ghosts is a horrible game but it's better than MW3 was.
