Think of your favorite SRPG

I would give it a world map. Towns. NPCs. Exploration. Down-time

My gut-reaction would be to just update Shining Force with Fire Emblem Awakening graphics. Which would make me completely blow my load in the end, for sure. But it could easily be done in reverse as well. Give Fire Emblem, Shining Force's exploration, towns, overworld, and all that jazz. And every other JSRPG ever

Ah...
