In case you live in a hole...
Wikipedia articleWiiWare is being touted as an avenue for developers with small budgets to release innovative, original, and smaller-scale games without the investment and risk of creating a title to be sold at retail (somewhat akin to Xbox Live Arcade and the PlayStation Store). According to Nintendo, the "remarkable motion controls will give birth to fresh takes on established genres, as well as original ideas that currently exist only in developers' minds". Nintendo will handle all pricing options for the downloadable games.
Like Virtual Console games, WiiWare is purchased using Wii Points.
This game would be epic with motion-controls and you could make new features to take advantage of all the Wii's capabilities.
Obviously, it would need to access music from the SD card slot.
Controls could be standard tilt action like Excite Truck and Mario Kart, but you could also get the Nunchuck involved... Perhaps move by twisting the Nunchuck back and forth (or using the stick, but that's boring) and then you could have the WiiMote free to point at the screen (to do character abilities)
I would buy this game again and again if it came to WiiWare. Think about it, wont you?
