I mentioned this awhile ago, but:
A current gen reimagining of Shining Force, Shining Force II, Shining Force III (all scenarios), Shining Force Gaiden, Sword of Hajya, and Final Conflict. Not specifically with super high end graphics, but with some reworked storyline, music, gameplay.
I think that would be fucking outstanding. Pop some actual towns into the Gaidens, some exploration into the original, some localization into the second game, actually GIVE US the second scenarios of SFIII...
Oh, my God.
Give it the Lunar SSSC treatment with a fucking nice box, soundtrack discs, a Yogurt plushie... If it was actually as good as I can imagine it, I would pay Sega $200+ for it.
