I think i have came upon 3 great ideas that the makers of the Call Of Duty should consider with their great games.
1) They should ad the option of being a male or female character and as well being character customization.
2) I think there should also be the knife part of the primary gun option should instead be attached to the gun itself. Imagine being ran at by someone and being attacked by their gun? That would be insane!
3) Finally, i think there should be the option of which hand (left or right) is used in controlling the gun.
I think these ideas would bring on the next generation of shooting games. Customization is a great way of setting players apart.
