What made the Mario 20th collection was that All Stars isnt availible anywhere else. With Kirby...most of the games aside from Dreamland 2, are either already on the Wii / 3DS VC, or have been remade. Wonder how they'll set them apart.
Maybe this one will have, like, menus and control configs... y'know, the sort of stuff every other ROM-dump ever has had. If they expect people to play with a sideways Wiimote like the did with the Mario collection then they're gonna have to.
