Okay, here me on this one. The ultimate face-off, Demons vs Robots. I know the NES game has alot of the graphics and sounds stripped from it. The game has Robot esque music, A sweet 1970's soundtrack. This game had a lot of love put into, it.
Remember in FFVII/VI when you had to fight a guardian creature. Like the one that made Shinra step back, for a moment, or blew him away.
In the NES game their are stadiums, where you fight a random enemy, but the PCE game has an small intro, where you fight a guardian, which you must be powerful enough to fight.
Dying is okay, because the force that keeps you alive, can revive you but dying and losing all your characters on the field yeilds an extra sad
ending, of the smallest/youngest ( like the guy who gets eaten/ turned into fairies in SOTBeserk ) demon, being slayed.
