I won't get into the quality arguments here, but I'm kinda confused at why people think that Nintendo isn't trying hard to get big name games. I mean, they got Monster Hunter 3 and Dragonquest X, which iirc, are the top 2 best selling third party games in Japan (Well, FF might be bigger than MH, but if it is, MH is pretty close). And wasn't Baten Kaitos published by Nintendo?
For those that are thinking Nintendo aren't trying on the first party front, well we have 2 more main line Mario games coming. There hasn't been more than one true Mario game on a Nintendo system since the NES, and Wii will have 3. You have teams working on Zelda, Pikmin, Fire Emblem, Wario Ware, and most other typical Nintendo franchises. Hell, even on the handheld front, DS is gonna be home to two Zeldas (even if neither one of them will be particularly good, but still).
I mean, if you don't give a shit about Mario and Zelda, that's one thing. If you expect more quality third party games, that's fine too, I guess. But to say that they're working less harder than they did with the GC, well, you probably seen one screenshot too many of Cruisin' World. Which, as a result has most likely caused one to view the GC's library in a better light than it actually appeared.
