Brave Battle Saga

Barver Battle Saga (aka Brave Battle Saga) is a traditional Japanese-style RPG. It features an ATB turn-based battle system modelled after Final Fantasy and Breath of Fire and an open, continuous game world similar to Secret of Mana.

Its story features a mixture of fantasy and sci-fi elements. It takes place in a post-technological society long after humanity has forgotten about the technology that nearly destroyed the species millennia ago. The protagonist Tim accidentally uncovers a cache of ancient technology which ends up involving him and his allies in a quest to prevent an evil empire from seizing the ability to activate ancient weaponry.
