David Braben, if you happen to not know who it is, was one of the guys behind seminal space-fest Elite - and Lost Winds is his artistically gorgeous download game for Wii Software.
In the game, you control the main character with the Nunchuck, and a second character (the wind spirit, in case you were wondering) with the Wii Remote.
It's a platform game, and the idea is you use the Wii Remote to manipulate the wind in order to progress through levels. It's also looking rather cool and is the Wii Software title we're most excited about. Go see!
