Without the Wii motion controls, Rayman Raving Rabbids feels completely ordinary.
To be considered a party game, there is a lot of focus on single-player component. That part is relatively long depending on how you look at it: the mini-games aren't that long but what made the game dull so many times were the loading times. Sometimes you feel as if they last longer than the actuall mini-games.
Now let's talk about the mini-games. On the Wii, these games take full advantage of that Wii-remote control, on the Xbox 360, you just have to play it with the control which is why most of the games feel lifeless. And they do, not only the fun aspect was taken away, but in some cases you will find yourself cursing the game for not being responsive enough or for implementing a control scheme that is ridiculous.
The bunnies do retain their quirkiness but with a lousy interface, Rayman Raving Rabbids has lost its charm completely. Don't bother playing this version, the Wii version is definitely the best and it's the way this game is meant to be played.
