I think the older games, such as Secret of Evermore, Secret of Mana, Chrono Trigger, and other SNES Square Soft games, should be updated using the new FF game engine. Remake the game, using the same story line, characters and other game elements, just updating the graphics.
I think that FF could grow/benefit from using those ideas. Like in Chrono Trigger they used 2-3 characters to make attacks like, Delta force, frog flare, and many more. FFXIV could make job combos like BLM+BRD= fire arrows and many other job combos.
