WiiWare demos are available to download once again. Nintendo of America has stealthily restored access to all fifty demos. They can be downloaded from the Wii Shop Channel right now.
Some highlights include: And Yet It Moves, the Bit.Trip games, Cave Story, Fluidity, Max and the Magic Marker, Pokemon Rumble, and World of Goo.
Nintendo discontinued the demo service on January 31st last year, saying "the demo program was always planned to be available for a limited time on a trial basis." We've reached out to Nintendo of America to see if this restoration is a permanent one, or yet another timed promo.
