Sure, we don't worry about what other people say about Gamecube, but all the casual people who read it DO. Everyone says that Nintendo is kiddy, and it's been said like that for so long that it has to be true.
While we don't mind, this isn't a good mentality to have when that is basically what drives people to buy game consoles. Adults buy more to their taste, and kids wanna act like grown ups. Nintendo doesn't have to make full on gore to break this, but they can at least try a different approach to making games. From what I've seen, some of their games (Nintendo-made, not 2nd party) are getting brighter and happier. Hell, SM64 was scarier than SMS, and OoT/MM was darker than WW.
I don't mind. But Nintendo are going backward. It all started with OoT. They made such a beautiful game in that, and the controls were excellent. It was even movie-like. Same with WW. But by blatently refusing to make games like that anymore, they are ignoring the reason why they are making a powerful next-gen console to begin with. Oh sure, we're going to have the most powerful console in the world, but that doesn't mean our games have to look the best. Then why make one? Just to satisfy the devcos that DO care? Nintendo at least have to try to make their games look as good as the hardware can provide. The gameplay can be simple, but if it is, at least make the game longer to accommodate US hardcore Nintendo fans. There really isn't a good reason to spend 100 bucks on a game that will only last 1 day.
