Revive the Ogre Battle series first and foremost. Hell, maybe even start with a remake of March of the Black Queen and fix the more clunky parts about the Ali/Rep/Charisma systems so stupid trout you would never know effects them without a guide will tell you what effects it, and give actual item descriptions.

Then update the game about Tristan we never got over here and give it to us.

Then give us a new game.

Then a new Mario RPG.

That would be a Square I could look forward too.
