I can't get a key for bfp4f.I'm thinking most people here are afraid of "going COD" means more simplicity. And devs adding "more depth" is just the amount of unlocks and customization.
I suggest everyone to take a look at battlefield online (play4free variant) to see what is possible with a dumbed down (no squads, but assault has a squad leader like unlock) yet expanded BF2 would look like.
ofcourse, when you're in the beta, I'm neliz there... add me to the friends list.
