The game originally started out as a classic adventure platformer game on the PlayStation 2 going under the name Rayman 4. When development switched to the Wii, the development team found the controls to be too different to continue making it a platformer. As such, the game was made into a party mini-game collection. Interestingly, the Game Boy Advance version of the game didn't change genres and remained a platformer.
The Xbox 360 version of the game has three achievements that are impossible to unlock: "Greatest Rayman Ever", "Rayman Loves Drawing" and "Rayman Loves Challenge". They all involve beating every challenge in Score Mode. To unlock these, the player must accumulate 174,000 points to unlock the final challenge, but the accumulated perfect score of every other challenge only goes up to 173,000.
