Since the game is classified as an “adventure” game there may not be much more to the gameplay. However, an early screenshot shows players using the Wii remote as a screwdriver to tune auto mail.
Fullmetal Alchemist: Prince of Dawn also does a fine job of rendering the characters in 3D. Click on over to the official site, click on “character”, then one of the floating heads, and finally one of the animations. While this may not be the kind of Fullmetal Alchemist game you were hoping for, Fullmetal Alchemist: Prince of Dawn has the living anime feel going for it.
