You should be able to allow the second player to look at their locker room and such. When one player presses the Start button, only that screen should be blocked, not the whole screen. Or if any of these are possible already, please tell me.
I just wish a guest could use my custom classes. Its not like he can level up and get them, he's a guest. Plus I'm trying to get my friends to get this game. Incentive? Maybe.
