If you're not extremely frusturated, then you can really enjoy this game.
You can collect clothes for your Rabbids, and there are some funny things. You can also design your background and color your Rabbid. There's no zoom option for either of these things however, which can make it frusturating.
The graphics aren't the best on the DS, but they're overall pretty good. The Stylus controls are pretty good, although sometimes frusturating. The cinematics are pretty lame, but can be funny too.
The game really doesn't have much of Rayman at all. You'll see him when you need to beat a highscore, in cinematics, and after you win a challenge. But he appears very little still, and the game might as well be called "Rabbids Raving Rayman" because they're the main characters.
The Rabbids are sometimes cute, sometimes ugly, and always kinda nuts, but oh well. What are you gonna do? Right? Yeah... they're not really the sharpest knifes in the drawar.
The challenges are usually fun, but they're sometimes very frusturating. In score mode, it can be hard to beat some of Raymans scores. EXAMPLE: In some games, you'll make it past a round, then it will show a little short clip, but the time still goes as the clip shows. This is annoying when you're low on time.
Pros: Good graphics. Some fun challenges. There are ton's of things to collect for your Rabbids. Very funny.
Cons: Adventure mode can be beaten in a few hours. It can be very frusturating. There isn't much of Rayman.
It's a fun game for Rabbid fans, but Rayman fans won't enjoy fully enjoy it.
