No replay value.
You play multiplayer, prestige twice, and then you say "Wow, I just wasted those hours playing a game, and leveling up, for no reason.... Now what?"
I like the BF series, it takes a while to get new attachments for a gun, there is Humvees, tanks, jets, quads, boats, a physic engine so you can take a building down, rater than dying 12 times trying to shoot down a sniper.
