Rayman 4
Rayman 4 was the prototype of a new Rayman game that would change of how Rayman's world looks like to this day, sadly due to the Wii coming out and Ubisoft wanting to release the game while the Wii was still being sold, and motion controls were new, they canceled the idea for Rayman 4 and made Rayman Raving Rabbids the latest Rayman game. Rayman 4 was going to involve the Rabbids invading your world, capturing innocent villagers, and try to sell them. In Rayman 3 when Globox swallows Andre, during mid conversation with the Tensies and Murphy (Not sure if that's how you spell his name) will say, "See you in Rayman 4!!", hinting that there was going to be a Rayman 4. There are still tons of unused content for the game that is still in the Rayman Raving Rabbids game files, such as animations for Rayman riding a snake, an animation Rayman holding on to something, a first-person mode, a black title screen that just says, Press (Start button or whatever button which could have been the beta title), and on Youtube there are even unused audio tracks for the game.
