The new Twisted Metal game is both a travesty and an abomination, but it does have really neat art design. Take a look at the concept work of one Donald Yatomi, and consider what might have been. Kotaku has the story.
Sweet Tooth was always a mascot character for Twisted Metal, but the game series went downhill when they started outright worshiping the character. The new game is all Sweet Tooth, all the time, and that really hurts it.
