While it was never a great fighter by any means, it was one of the Playstation launch titles was used to showcase how amazing the Playstation would be. Every ps1 ad leading up to the launch featured the game. Sony put a lot of marketing money into it. Then it just faded away.
So I think it would be appropriate time to bring it back with the new system and with Microsoft also bringing back a fighter that also was a showcase game that faded away.
It's kind of amazing that there've only been two Power Stone games and that both have only ever been released on Dreamcast. Power Stone was very dependent on getting friends together to have fun as it had no single player at all, or at least none worth playing for anything other than practice. It'd be perfect for modern day online gaming. Come on Capcom!
They were both ported to the PSP.
