Baten Kaitos: Eternal Wings and the Lost Ocean

Baten Kaitos: Eternal Wings and the Lost Ocean is a role-playing video game developed by Monolith Soft and tri-Crescendo and published by Namco for the GameCube. It was released in Japan in 2003, North America in 2004 and PAL territories in 2005. The player assumes the role of a "guardian spirit" – an unseen player avatar – who guides protagonist Kalas and his party of companions in an adventure across an aerial floating island-based kingdom in the clouds. The game is focused around the concept of "Magnus" – magical cards that capture the "essence" of items found in the in-game world. The concept is used as a plot device, for in-game item management, and as a basis for the card-themed battle system. The game was noted for its unique battle system, which included aspects of turn-based and action-based battle systems, collectible card games, and poker.
