Final Fantasy Hacktics

Gigantor map! I dig the ambition.  It's a little bland, but that could be fixed with ruins of a fort or something similar.

Or a full fort. Doesnt have to be ruins.

I wonder, could we double the resolution and the size of the currently existing battlefields?  Like a HD Mandalia?

It's possible, but I don't know what kind of approach could be taken to updating the actual texture to have more depth.

Yes we can, but it is a tedious job. We have to add more polygons, double the size of the texture, double the colors of the palettes, and edit the textures to make them smooth and more detailed. Nobody wants to spend ages to double the resolution of a map, except maybe on a small map, for a demo.
