It actually had an interesting plot, far better than most of the nonsense you see in today’s game (a bunch of people have some crazy reason to compete in a tournament, everyone wants this item of power, etc).
The plot involves dead warriors that died before their time and are given the chance to redeem themselves by the Eternal Champion and get a second shot at life.
The best part about this game’s plot is that it allows you to pull ideas from any part of history (there are characters all the way from the Stone Age to the future.) and it all makes sense.
Game like this could really use a revival (ie remake or sequel), the basic premise alone could allow for fresh stuff.
Plus I think the training mode and full bios for characters were miles ahead of its times.
