I can see F-Zero being bump up to being one of Nintendo's 1st tier franchises (Pokemon, Zelda, Mario, Mario Kart). The game is just jaw dropping. This game has the flash that Denis Dyack said Nintendo and Silicon Knights needs in their games. Being a racing game, the game would appeal more to casual gamers. Also, being multiplayer is a big plus. I think that F-Zero has a chance to outsell Zelda this year, but Mario Kart will be the best selling GameCube game this year.
