Rayman Origins is available on all three home consoles and features gameplay that is most comparable to the first game in 1995. It is also the first game to be built using Ubisoft's UbiArt engine.
On Xbox 360 and PS3 the game features a very crisp 720p image while the Wii features a very pleasant 480p image. All versions of the game run at a constant 60 fps without the slightest frame-drop or screen-tear. Even with multiple characters, layers of scrolling, and effects running the engine never faltered on any of the platforms.
Graphically, the 360 and PS3 version are identical; there were times where I would switch the video input back and fourth and would pick up the wrong controller because I was confused which feed was running. Neither system had the normal quirks associated with other cross-platform titles. The Wii version, of course, runs only at 480p but is still quite a sight to behold. No matter which version you play, you are getting the best performance available so there are no clear winners in this category.
For sound, we get the normal platform separation. The 360 features Dolby Digital 5.1, the PS3 gets up to Dolby Digital 7.1 PCM, and the Wii has Dolby 5.1 ProLogic IIx support. Essentially, the maximum support has been given to the hardware's capability. The PS3 wins the sound category here.
Gameplay, much like the graphics, are also identical. There isn't a clear winner in this category, either, so it comes down to personal preference which form factor is most pleasing to your hands. For the record, I prefer to use the Wii's Classic Controller Pro if given the choice since this is a strictly digital-controlling game. That being said, it's a three way tie for gameplay.
Rayman Origins the single most adept cross-platform game released. The PS3 version edges out the other version by virtue of it's maximum supported sound capability. It doesn't matter which version you purchase, though, as you will be receiving a marvelous, marvelous game experience. I would high recommend you buy this game.
