yeah I was just thinkin the same thing with mario golf already out. Its true also that if you were to try and get sports game back into your business, golf is not where you start. Besides, startin up a sports side for the company isnt too smart given how poorly they sell on the console and something of that nature is better left for the next gen where they can have the games come out as launch titles. As far as I can remember, left feild used to do the sports games for nintendo.
As for the game being a parody I aint sure. For that type of game, the graphics engine for it would have to be somewhat cartoony I would guess given its humorious nature and we all know how much controversy zelda had with wind wakers cartoon graphics. Using that type of engine and theme I dont think will sell well for a new original game even though I would love to see it happen. The idea is interesting and would be good to see given how much fun I had with conkers for n64 (the only game I can think of that was a parody as a whole lol).
I'm really hoping its a "darker" or more "mature" adventure/rpg resembling zelda. Given that it'll be a original game would allow them to not hold back and use some themes and presentation not possible with zelda becuase of the image it has to uphold. Given the success of Star Wars:KOTOR and the hype for the upcoming sequal plus Fable for xbox, I think now would be a good time to come out with something for the crowd wanting more so called mature games for gamecube.
