I completely understand why nintendo does it, its just frustrating as an older gamer with no friends who own wiis and buy games. If my friends were really into their wii's and bought games a lot then I wouldn't mind at all. But adding people from a forum in mass, hoping some of them will add you too, can be painful.
What they could have done was add an option in parental controls to use friend codes or opt to them not being necessary.
I guess I just don't have any games which stress online. Can't wait for mario kart.
