I don't know if you can compare Gameboy with GameCube but I bought a Mickey Maus game for Gameboy before about 8 years and I never finished it. It was too difficult!
I still cannot understand what good gameplay Mariokart and such games can have?
I guess, I would be bored of them after a short time. The only Racing Game I like is a game with real cars and not those in MarioKart.
I think there will be a similar game in the next year(s) but not such a game called Battlefront 2.
I guess, they will call it a other name than Battlefront 2 because it would sound a little bit like Battlefield 2.
