If you played the original you'd probably notice where the problem lies. The Saturn version had such tight controls and a subtle but engrossing storyline, and somehow, despite ten years of advancing tech they managed to make the game control less tightly, the whole story was convoluted and held your hand throughout, and Sega's love for gimmicks overtook the core gameplay mechanic.
The game had potential, it looked great in the first video's that were released, but then too much unnecessary bollocks was thrown in.
Anyway, enough of my fanboy whinery :P One Wii game I love was the original Excite Trucks. Easy on of the best multiplayer experiences I remember having on the Wii, and it just brings back that "new console feeling" every time I pick it up. Never got the chance to player the other Excite games but if I ever pick up another Wii it'll be on top of the list, right next to DKC Returns.
