you should say something more directly about casual gaming being complicated with friend codes. like : The casual market Nintendo is drawing in may not have the patience to input Wii numbers and individual game friend codes, and this could turn them off to the entire online experience. With hardcore gamers also dissatisfied, it would be beneficial to everyone, including Nintendo from a pure business standpoint, to simplify the friend code process down to a single unified user-name, or at least let people access the friend codes of their random opponents. This would satisfy everyone, and also boost Nintendo's online efforts.
PS since Nintendo didnt give 3rd parties access to online features until a year after the wii's release (which is november 9 2007 right? or 19?) i wouldnt be surprised if we saw a tremendous revamping of online efforts shortly after. say...super smash bros brawl shortly? or possibly with an ambitious 3rd party effort. i have my fingers crossed.
