Summon Night 3

Third game in the strategy RPG series Summon Night. You take the role of either a male or female summoner assigned to protect one of four selectable characters in a trip to a foreign land. Falling under a pirate attack you end up stranded in an unknown island, and now you, your ward and the pirates must fight their way to freedom and uncover a few secrets in the way.

The game uses a 2D isometric engine to portray the main characters in the world map as they explore each location chatting with NPCs for clues and items, and switches to a tile-based map for combat in which you arrange your party and battle against the many creatures and enemies you run into using spells, attacks and summon abilities. The game now allows you to turn yourself into a your guardian creature, which augments your abilities considerably. But using this morphed form too much has an effect on which ending you receive (as does which characters you select at the beginning of the game).
