It's an interesting game. Developed by MS Japan and released over there, it went through a complete English conversion before it was decided to can the USA release. Majesco swooped in and bought the rights cheap, so it is shelving here tomorrow at a price of $19.99.
The game seems to be part Otogi in wow graphics and action, part Magic the Gathering (cardgame) for gameplay, and part Akira (the movie) for feel. You basically play an uber human that slects his powers and does battle with other uber humans in the wreckage of society.
