Metal Max is a role-playing game series produced by Crea-Tech. Due to copyright problems, the series was split into two sub-series, "Metal Max" and "Metal Saga", with Metal Max being generally the main one. Metal Max was initially published by Data East, and later the "Metal Max" trademark was acquired by Enterbrain and the game was published by Kadokawa Games; Now Production and Enterbrain then published the portable versions of the games. Instead "Metal Saga" is a Success Company's trademark.
