Is the Wiis sound similar to some GameCube games in the sense that they are MIDIs on steroids (think: Metroid Prime)?
No, for the most part our Wii audio experience has been pretty good. Excite Truck has real, honest to goodness lame rock music. The sound coming out of the Wiimote, however, is another story entirely. It’s pretty awful. We’re not sure if that’s due to Bluetooth bandwidth restrictions or a really awful speaker, but man does it remind us of a Game Boy trying to make real audio sound effects.
