This game looks cooler on TV. It is NOT that fun in real life.
In all actual reality, the only motion control you use is the nunchuck and you use it to jump up and down. Other than that all you do is go around and break ice blocks and other dumb big dinosaurs. You can destroy the villages but it looks terrible and lame and all you do is push the A button.
It's a really dumb game, you don't want to buy it or rent it...but definitely watch the commercial for it over and over again, because it looks sOOOOOO cool!
