The Mummy: Tomb of the Dragon Emperor for the DS is based on the blockbuster movie of the same name. The problem is that the movie is a visually intense action thriller. The game just can't live up to it, and doesn't. It doesn't stand a chance on a handheld, simply due to the lack of processing power. In such a case, it's almost unfair to compare it to the movie, but it seems that it's what the powers-that-be wanted.
