Phantasy Star Online 3: Card Revolution, released for the GameCube in 2003, deviates from the classic action RPG elements of the Phantasy Star Online series. This spin-off introduces a strategic card-based battle system where players collect and use cards to battle enemies. The game combines the lore of the PSO universe with a unique turn-based gameplay, offering a fresh experience while retaining the sci-fi atmosphere. The hybrid of card collecting and strategic battles with multiplayer options makes PSO 3 a standout title within the GameCube's library.
