Kirby's Dream Collection will dreamily collect several classic Kirby games starting September 16 in North America. The Wii set includes emulated versions of Kirby's Dream Land 1, 2, and 3, Kirby's Adventure, Kirby Super Star, and Kirby 64.

Unlike the Super Mario All-Stars special edition, which was just an SNES ROM on a disc, this also comes with exclusive new material, like challenge stages in the Kirby's Return to Dream Land engine and a virtual museum/timeline. The collection also includes a soundtrack and a booklet.
