This release walks a fine line between an updated version and a full remake of KO Seiki Beast Sanjūshi: Gaia no Fukkatsu. The game follows the same story for the most part, and contains the cut scenes from the original version. Like most PC Engine (TurboGrafx) CD games, it features voice acting during cut scenes and CD audio tracks.
Several cut scenes were added, and some dialogues expanded. Though the story progression and the areas the characters have to traverse in order to advance it remain intact most of the time, the gameplay system has received an overhaul, being essentially developed from scratch. The “RPG-lite” feel of the original version is now somewhat compensated by the ability to equip weapons and armor, as in most RPGs. Combat engine has also been modified; instead of the isometric battle screens of the original, the battles are now viewed from “over-the-shoulder” third-person perspective, with player-controlled characters visibly attacking the foes, similarly to Phantasy Star IV.
