I'm really amazed at how misinformed some xbox/sony fanboys can get...
The wii controller isn't special because its RF; There have been RF controllers since the NES (maybe earlier). Nor does it just have accelerometers like the PS3 sixaxis (lol). The console "knows" where the controller is in three dimensional space.
Re kiddy games/underpowered graphics:
If you have a serious problem with playing a brightly colored game, or a game that uses sprites, or a game featuring an old Nintendo franchise, I feel sorry for you. Demographically, you're most likely a highschool aged male who reads Maxim for the articles. You're probably insecure about being a wuss and a nerd. Even if none of that applies to you at all, you're still missing out on some STELLAR games that go unmentioned because 90% of the mainstream play just a handfull of titles (GT, GTA, FF, MGS, halo, Madden). I can't watch Nicholas Cage movies the way some people can't play Mario. That means every now and then, I miss a movie that is really something (adaptation, the weatherman). The least the PS3/XBOX set could do is cop to the fact that know they are missing great games.
As for the graphics: Gears of War looks really nice. So does the New Final Fantasy. Still, the game I want to play most on the 360 is geometry wars.
thats just me, though. Seeing really high poly counts and gigaflops is pretty amazing. Moreover, when something looks that good, you can be assured that the other production values are going to be pretty decent too. They are the Summer Blockbusters of the gaming world. The metaphor works farther than that too. They are targeted for the widest possible audience. They take VERY few chances gameplay-wise, and they take a VERY VERY long time to produce (nevermind the money). The consoles themselves are sold at a loss because of all those polygon and texture elements. Nintendo continues to make a profit with each console sold, and they can also turn out some interesting games that didn't take a company with the resources, or the bean-counters or say, an EA, to produce (Viewtiful Joe, Warioware).
Nintendo also absolutely stomped Sony in the Handheld market. Major retailers have stopped carrying UMD movies, and worldwide PSP sales lag behind the DS (sold for a profit, while the PSP is sold for a loss) by 3-4 million units. They're hoping with the Wii that innovation and low developmental overhead will draw quality titles and new gamers who don't just want to play the freshest FPS or "GTA: this time you're asian".
I'll be playing the Wii for the first time tomorrow. I hope I don't throw my back out.
