I'll admit you have to be careful what you purchase, which is why I think the Nintendo Channel for the Wii has become a great addition. You get to see how crappy Wii Music is before you rush off to the store!
In comparison, however, you also get to see what fun and beauty is also out there; case in point would be Tetris Party. Ok, yeah, maybe there's NOT a lot of difference in it and Dr. Mario online. Tetris Party, however, will surprise you with its varied game play styles (including Wii Balance Board, which is what got me curious / sold me), and it's ability to host online tournaments at some point in the future.
The balance board game is fun and more than a challenge for someone old as myself. If there is any disappointment I have with it it's that the T-shape pieces are not included, but I suppose they couldn't figure out / didn't take the time to figure out what balance board movements would be needed to place those - either that, or the moves were too difficult.
I'm a puzzle game fanatic, so don't take my review too seriously, but I am more than impressed. Only cost me the equivalent of $12 too (1200 Wii Points). It's a nice offering for such a cheap price. When I can afford it, I hope to try out Amazing Maze by Digital Leisure (yet another balance board game) as well.
