Y'all are so hung up on whether or not Zelda is a killer app. that you're completely missing my point. I don't care if it's a killer app. I already said it can be a killer app. if you want it to be. I'm sure that I was a bit hasty in suggesting that nobody was buying the system for Zelda. I'm sure I'm wrong about that (it ain't anything like 19 out of 20, but whatever . . . Zelda's got a lot of hardcore fans . . . ).
My point is simply that the first party studios of all three companies dropped the ball, which is strange considering the advantage they have over 3rd parties when it comes to launch games, with early access to dev kits, etc. This applies to Nintendo regardless of whether Zelda is a killer app, because while they ported a great game to the console, their first party studios still failed to complete any kick-ass games to show off what the Wii is capable of, and no, Zelda does not accomplish this -- not in graphics nor in control.
Zelda: Twilight Princess is better than any other launch title. But Zelda: Twilight Princess for the Gamecube will be better than any other Wii launch game as well. It is the same game. It is a kick-ass game, and Nintendo has turned it into a temporary exclusive by arbitrarily holding back the long-completed Gamecube version, which certainly gives impatient Zelda fans one more good reason to pick up the Wii. And I even suspect that some aspects of control on the Wii version (bow & arrow, hookshot, fishing, etc.) are superior to the GC version (while certain aspects are possibly worse -- swinging the sword and camera control, for example). I retract what I said about Zelda not selling systems, but it simply is not the killer app we are used to from a Nintendo console launch. To put it simply, it is not Super Mario Galaxy, a game that was built from the ground up around the Wii hardware, and built from the ground up to take advantage of the Wii remote, rather than simply taking a game developed for a gamepad and mapping gestures to gamepad button presses. And it is a game that was originally planned for, and should have been ready for the launch.
But whatever, I guess . . . I seriously don't think we disagree on any of the facts. We just interpret them differently, I guess. We all probably feel exactly the same about the quality of Twilight Princess -- it's great*. We all probably agree that Nintendo failed to ready Metroid, Mario Galaxy, Warioware, Battalion Wars, Mario Strikers, Cooking Mama, Mario Party, or Smash Bro. in time for launch. Every one of these titles is being developed from the ground up for the Wii, and every one of them missed the launch. Any one of them could be the potential killer app (aside from Strikers, I suppose) that really shows off the Wii. Zelda is a killer app, but only for the reasons it will be a killer app on the Gamecube. It's just a high quality game, but it is not THE game to make you fall in love with the Wii hardware. If anything, that chore probably falls to Wii Sports or a 3rd Party game, and none of those, IMO, really do the hardware justice.
*I've never actually played Twilight Princess so I suppose I could end up disappointed with it, though I REALLY doubt that will happen.
