Summary: This game will definetly NOT appeal to hard-core gaming fans, but fans of BIONICLE(which I am) and Kids should like it. It's fairly easy, but we just recently got an Xbox and this was the first game we tried on it(you can't try something like Halo and expect to be good at it right away). BIONICLE fans might find something lacking about it, and I'll tell you: Not enough levels.
Summary: My 6 year old son is a Bionicle fan, and he also loves platform-style games, so this title is a perfect fit. I think that, for the target audience, the game is well done. It is short; my son beat it in two days all by himself (except for two fights that I did for him). It might be better if it were priced in the thirty dollar range, because of the length. But there is a good mix of action/platforming gameplay involved, and it never gets too difficult.
