We love Line Rider on the PC, and the Wii version looks pretty groovy too. I just don't know if I'm down with all of that art work and such, I'm sure someone will be, just not me. Here's hoping the next video will actually show how the Wii remote is used, like with the action happening as someone uses it. I'm intrigued.
Update: Turns out that this is indeed the PC version, despite the fact that it was placed in a folder for Wii videos. Sorry about the confusion.
