FPS is where you will find me. if it didn't atleast come with a option I probably wouldn't buy it.
I pretty much hate fps. I find them all to pretty much be same game. Even among the fanboys, no one can deny that at the very least, ur character is the same in every game. a hand holding a gun or simply the end of a gun. not that that matters greatly to some i suppose.
One of my biggest (AMONG MANY) gripes with fps is the lack of periphreal vision. In real life i can look straght forward and still see slightly beyond what is straight to either side of me. For me 3ps better mimics this "awareness", something especially essential in battle
need i say more about my answer ?
With such a great game, I think it's always best to change as little as possible. Keep it 3rd person with the option of 1st. It doesn't bother me playing 1st person shooters, but I have friends that avoid games that restrict you to 1st person. Cutting down on the likabillty of a game is not a good idea, especially when it works so well the way it is.
