Honestly, the graphics still kinda hold up. And if they would keep the same style then I'd wish for something like Octopath Traveler.
Personally a remake would need a couple quality of life additions. Like no random encounters, option for auto-battle, etc... Just please pleeeaaase for the love of all that is holy, don't make a spectacle fighter out of it. Turn-based is fun if done right and should stay a staple for JRPGs.
