Wii Play by itself is just $10, with a $40 Wiimote? Ooooooookay...
A few of those games were funny, but most of them were just plain wrong. The Mii in "Why are Wii Hitting Ourselves?" was in a padded room. I think the last one shoulda been called "Wii Have a Problem Again". Were these really proposed games for Wii Play? Or are they just a prank by some YouTube user? So that's what a baby Mii looks like...
I just realized something! The music at the start of the video... It's the opening music for Wii Sports. Funny.
