Xenosaga Episode I - PS2 Trailer [High Quality]

This 2002 sci-fi RPG features strategic turn-based combat where visible enemies eliminate random encounters. You manage AP/EP gauges and use turn-order previews to plan actions, with a "boost" system allowing turn interruption. Progression involves learning Ether spells via a prerequisite tree, and characters can pilot equippable Anti-Gnosis Weapon Systems (AGWS). The story follows scientist Shion and android KOS-MOS after retrieving a powerful artifact, involving espionage and the search for the lost planet Miltia.
