I'm only reviewing the multi-player aspect of this game, as it's the only part I've played, and ultimately I believe this is what the Wii is made for. If you're playing solo most of the time, then you might not agree with my views with this game, or the fact that you should get out more.
This game is great fun, whether you are with children or adults, drunk or sober. Most of my comparison of this is with other party games such as Raving Rabbids 1, Mario Party and Super Monkey Ball. The first great thing you notice is that you don't have to play for ages on your own to 'unlock' the multiplayer games. Just open the box, put it in your machine and choose the multiplayer trip with your friends.
I'm sure most people will also agree that the Rabbids characters are much funnier than the Mario characters and the Monkey Balls, and the activities and noises they get up to reflect this. However, comparing the mini games with the original Rabbids, most of them are more straight-forward, and I guess this is why some reviewers have said they lack the need for any skill. However, what they lack in skill they make up for in fun.
For example, running from the boulder game simply involves moving remote and nunchuk up and down as fast as you can - yes, no skill needed whatsoever - but the fact it leaves you and your friends with cramp in both your arms and in your stomach from laughter makes up for that.
Yes, the games aren't all perfect. There are a few games in the original Rabbids which are better, but looking at the whole package, I believe this sequel is much more playable and overall more fun.
