A snippet from Eurogamer's review:
"If you didn't enjoy or just weren't interested in the first Rayman Raving Rabbids game, the second is not going to change your perspective. Some of the new mini-games are entertaining, but too many are too similar to those in the first title. In addition, too many are based around simply shaking the remote. There are much better mini-game collections out there - such as Mario and Sonic, unlocking nonsense and all.
But if you loved the wacky humour, range of mini-games and stupid rabbits in RRR, you'll like this. There's still an argument for considering other mini-game collections with better ratios of good-to-poor games. The ratio in Rayman Raving Rabbids 2 isn't even as good as it was in the first game. And overall the game isn't as entertaining as a rabbit doing a poo on a stage, which should tell you something."
