Tales of the World: Radiant Mythology (テイルズ オブ ザ ワールド レディアント マイソロジー Teiruzu obu za Waarudo Redianto Maisorojii?) is a spin-off of the Tales action role-playing game series for the PlayStation Portable. Like some of the previous games that bear Tales of the World in their titles, this game is a crossover title featuring characters from various Mothership Titles. Unlike other games in the Tales of the World Series, however, this one has been released in both North America and Europe. The game's characteristic genre translates to "For Your Sake RPG" (きみのためのRPG Kimi no tame no RPG?).
