The game is set in the same universe (inspired by Japanese animé) as the rest of the series. Like all its predecessors (except the second game), this is a strategy RPG. The story unfolds in dialogues, and the largest bulk of the game is occupied by strategic turn-based battles. The system is called Action Order Battle (AOB). Every character in your party has action points. Depending on their parameters, he (or she) can execute a certain amount of actions: moving, attacking, casting spells, etc. The character receive experience points not only after battles, but after defeating enemies, or even after inflicting damage on them.
