Rayman 3D is an 'adaptation' of Rayman 2

Tucked away in Ubisoft's 3DS lineup press release is this golden nugget: Rayman 3D is actually an "adaptation" of the classic Rayman 2 (the Dreamcast version, specifically). Those of you who have experienced the joy of Rayman 2 can probably stop reading now. The rest of you will be glad to hear that the 3DS version will feature "major updates" to certain gameplay elements, including "accessibility, progression and learning curve."

Frankly, we're just glad to have a new excuse to collect Lums again.
