Using a new technology called the "Pollux Engine Square Enix has created a true cross-platform game as it will be identical on both NDS and Wii, down to the last detail. Use the stylus to control your character on the NDS while the Wiimote will mimic the same actions when used on the Wii. The game requires only one copy of the game to work on both systems and will be multiplayer compatible on both platforms.
