Pilotwings for me. I loved Pilotwings 64 an amazing game.
Seems like a game that could really work well with the gamepad too.
They could combine the features of pilotwings 64 with wing island and propeller arena and do a cartoon flight and dogfighting game with lots of extra levels like the original pilotwings 64. You could have online dogfighting with mario, yoshi etc all in their own biplanes. Stunt levels, open world flying, jetpacs, gliders, rocketsuits, gyrocopters. Perhaps even airships, jumbos and balloons. There seems massive scope for a really fun game.
I'd much prefer something like that over 1080 or waverace especially as my memory of waverace on the gamecube was a horrible game that didn't control anything like the brilliant feel of waverace 64.
