Ghosts is by far the greatest cod ever.
I love the game because you can shoot first and still get melted.
OT: I think that BoII is prob the best game to pretty much do anything in.
It is really good to hold stats on. (Except for the retards the do bot lobbies. *Cough Cough* Gzmertag)
I just really enjoy how the game plays, It's usually smooth unless you get a ****** host then the game is shit.
