Blazing Angels is a WWII based game where you are a pilot, it's really fun flying the plane with the nunchuk and it's a cheap game (like $20 at wal-mart) I just wish you could play it online.

It is multi-player tho which is kinda cool, but not the best.

Twilight princess is amazing and I recommend wii controls. But if you insist on using a gc controller, you have to buy the gc version.

Try Metroid Prime 3 if you're into shooters. The wii controls are great for that.

And Mario Kart isn't that great imo. I only play it if a friend asks for it.
