I think the way characters should be unlocked is when you beat the game with a certain fighter you have the option of 1 of three or so characters to unlock. The thing is the chracters are differnt per character you beat the game with. And away to trade characters online and such. Also i think weapons should be chosen along with alternate outfits when you choose your character, however you can trade found weapons and outfits over the internet also!!!

Also they need to find away to block hackers from hacking into the files to blow the surpise that there are no SU's
