When purchasing it I got it confused with the German version of Rayman Forever, which is essentially Rayman Collector, complete with the 60 new levels. I messed up
Rayman's World is the German version of Rayman Designer, which mean you have those new levels (yeah, the really hard ones), and the mapper, without a copy of Rayman 1 to go with it. So it's less then Rayman Gold

(unless you have that lousy musicless Focus interactive version - in which case...it's a whole lot more!)
EDIT: It's a lot better then the version of Rayman Designer that comes with Forever - with the full PC soundtrack (this means I don't have to put with a random track from the Caves of Skops as opposed to Dream Forest music, and the Picture City medley is in full instead of playing the violin track on a loop). Also, while play testing the game - I just won a level of Rayman Designer for the first time ever! I've never been able to win a single level of it in the past! This means my Rayman skills are improving....
