well I think the main reason that Nintendo games sell so well is because they're Wii games. I mean, no REAL gamers buy the Wii, it's all toddlers and grandmas, and most of them buy the Wii Sports games because 'lolmotioncontrols', they buy Wii Fit because they're pretending to be getting in shape, and Wii Play because it came with another controller at a time when getting a controller was hard.
Then there's MAriokart and New Super Mario Brothers Wii, both of which are easy to pick up, 4 player games.
seriously, would ANY of you actually buy Wii titles because you want to play them? Wii fit maybe, but that's not really a game, that's a digital workout trainer. I may have enjoyed my Wii Bowling time, but I certainly wouldn't have paid for it.
