Just picked this game up last night and it's fantastic. Highly addictive game that has a variety of puzzles and modes, but nothing beats the multiplayer vs. mode in which you can have up to
EIGHT people playing at the same time on the same machine. They achieve this by having four people use the Wii-motes and the other four people use the nunchucks.
It's also cheaper than most new games (40 bux instead of 50). I highly recommend you buy it NOW.
