Nintendo needs to stop making Valentines to the N64 fanbase. Twilight Princess was a 'valentine' to those who loved Ocarina of Time. Mario Galaxy is going to be a valentine to those who loved Mario 64. Sure, both games sold many copies but these games go against the nature of the Wii itself. These games are also very expensive to make, and it is not worth the time trying to pacify vocal, raving fans. The vocal, raving fans will never be satisfied. They will just get louder and more vocal for the next game.
You would not believe how many times some lapsed gamer would ask me, "Is a new 2d Mario coming to the Wii?" I mention Super Paper Mario, but they won't accept that. "Tell me when there is a new 2d Mario on the Wii and then I will buy one." 2d Mario is the killer app of all killer apps. It just doesn't feel like a Nintendo console without some sort of 2d Mario on it. The DS began to take off in America not so much because of the DS Lite but because of New Super Mario Brothers. It has sold 4.1 million in Japan alone and, I believe, 3 million in the United States.
Mario Galaxy will not be selling those numbers. It will probably sell to a minor audience in Japan, do much better in the West, but everyone will be wondering where the 2d Mario is. Look at the success of Mario Kart DS. It was designed to 'beat' the SNES version (not the Gamecube version, not the N64 version). Even Yoshi Island DS's strong sales should indicate to Nintendo that there is an audience raving for classic 2d gameplay. This is one of the reasons why the Virtual Console is so popular.
Why must 2d be exiled to handhelds? They can keep making the 3d incarnations, but I would like to see the 2d incarnations return as well. 2d Metroid and 2d Zelda would also be welcome on a console. The 2d games are much cheaper to make requiring less size of a team. Super Mario Brothers 3 was made with... 12 (?) people.
BTW: Bowser JR. needs to go. Bring back the Koopa kids and their airships.
