hmmmm yep i guess it would depend on your tastes Lifty, they might look similar but play quite differently in general, the battlefield franchise in general is more geared to squads and playing as a team toward common objectives while the whole COD: MW thing is more just run and gun, both have their pros and cons but i prefer the battlefield thing with its cap and defend, awesome vehicles you can hop in and the character classes which actually have to be used effectively to win.
btw, love that sig lifty, I loved that movie!!
