Another potential franchise start here by Sega that went absolutely nowhere. It is almost painful looking back on Sega's library.
I would have loved to see them mix in other Sega games into the helmets system. Could you imagine finding, say red shoes, and your character puts on a Sonic costume but can run fast? Or picks up a sword and transforms into a muscular character similar to Axe Battler from Golden Axe?
So much potential with this game and Sega missed it completely.
