4. Luigi's Mansion
Released as a launch title for the GameCube, Luigi's Mansion could never stand up to the might of a proper Mario title, but that didn't prevent it from being one of the most entertaining GameCube games we played. On the Wii we'd hope for some proper Ghostbusters-style ghost zapping action, with the game perhaps coming with a ghost catcher peripheral. This game might not be high on everyone's list, but it single-handily made the GameCube worth owning from the beginning. We'd love to see what Nintendo could do with the idea on the Wii.
F-Zero on the GameCube still ranks as one of the best high-speed racers ever made, but the series has been lying dormant for years. SEGA's Amusement Vision managed to create a stunning looking GameCube game, so building on the same engine, tweaked to take advantage of the Wii's extra horsepower, should be enough for a solid looking Wii game. Online play is essential, as is a tight control scheme. Nintendo is keen to get everyone playing on the Wii, but F-Zero might be better left in the hands of hardcore racing fans. Tilt controls in such a fast game is surely asking for disaster.
