Trickster Online

A F2P (Free to Play) 2D, isometric MMORPG by Korean developer Ntreev Soft. The characters compete in a "contest" to win treasure on an island organized by the late Don Cavalier. The story as a whole is heavily influenced by Greek mythology. Each section of the plot is split up into 6 episodes each unraveling a portion of the final story, which ends up being more than just a "treasure hunt".
