Tales of the World: Radiant Mythology is a spin-off role playing game of the Tales series and is the first one in the spin-off series to be released outside of Japan. Like the other spin-offs, Radiant Mythology is a crossover title featuring characters from other games in series which are playable and interact with eachother. The game uses the Flex Range Linear Motion Battle System found in Tales of the Abyss. Unlike other games in the spin off series, you can create your own character to be the protagonist. In order to progress through the game the player must do missions in a variety of dungeons including killing certain enemies, fetching items, etc.
Tales of the World: Radiant Mythology seems to have occurred before the stories of some of the Tales Characters in the game ever occurred. Some of the characters have finished their journies before this, but it is not actually mentioned. For example, a skit occurs with Kratos acting fatherly to Lloyd, and Raine tells him that he is acting very fatherly. Mormo later agrees, and asks your character. Regardless of what you say, Kratos will sigh and leave.
Later, Chester Barklight tells you that you are becoming a good Swordsman (only available if you picked the Swordsman class), but you will probably never match up to his friend, a legendary swordsman. Arche also tells you that Chester has lost his sister, and is now looking after Kanonno, trying to find a way to replace Amy.
After you create your character, than you start the game with a small animal named Mormo talking to you. It will tell you about Yaoon, it's world, and how you were just born from Terresia's World Tree. You then find a scream. After a battle, you meet a young girl named Kanonno. She has lost her memory. Afterwards, you meet Chester, and he tells you to go to Ailily's Ad Libitum. When you arrive, you meet Ganser, the leader of the town, and you learn about The Devourer.
