Was hoping for a lot from this game when I bought it, and was very disappointed. The song selection is very small and the tracks are poor recreations of the originals - I have heard better performances from amateur bands at my local pub. I get the feeling that this game was put together incredibly low budget and had very little involvement from anyone who is musically talented.
Let's begin with the dance-off:
For a start, the metronome clicks from the WII remote are out of time on most of the songs, I had to turn the remote volume off to be able to get a decent score. Otherwise you spend the whole track trying to listen to the 'tick tock' instead of the song. You swing the remote up, down, left and right in time with the music to fill your boogie meter. Then you can do combos by... yet again swinging up down left or right. You can also move around the stage to collect 1 of 3 types of powerups. This sort of gameplay is only challenging if you are incredibly young or very drunk and is of little interest to either category. My six year old son-in-law played this game with his friends once and was bored and asked to go back to WII sports instead.
Then there is Karaoke:
This is very similar to singstar, with the lyrics at the bottom and coloured blobs representing pitch. However there is only one microphone which means no multiplayer, and it is difficult to convince people to sing on their own at parties when they might have otherwise been persuaded to join in with a friend. Furthermore, during parts of the songs you can hear the artist singing, but no blobs to sing along to (and I'm not talking about the Grease track with the option of singing either male or female). The game doesn't recognise pitch very well, and you can basically have one player talking in a monotone, and then another player singing in perfect pitch, and their scores will be very similar.
Finally the Story Mode and Shop:
When you first start playing, most of the songs, stages and clothing is locked and you have to purchase them at the shop or unlock them through story mode. Because of the funky cartoony look of the game, they could have put in some animated scenes during the story mode that would have made it interesting (think of Wario Smooth Moves!). Instead you are presented with one background with static character pictures and about 100 words of boring text to read through. In the end I just ended up skipping the text and breezing through the challenges to unlock the feeble number of tracks available in the game.
My advice to anyone considering buying this game is:
Another classic rip-off cheaply produced title from the corporation that destroys smaller games companies. R.I.P. Bullfrog.
