Completely turn based or active time battles. 1080p to 4k 2D sprite graphics. Set in medieval times. A great soundtrack by Nubuo Uematsu... I may have his name spelled wrong. No pretty boy teenagers. Normal towns with shops. The Final Fantasy theme music and classic victory theme music. No DLC. A complete game in a package.A real FF, unlike XIII and XV.
This is why I play Brave Exvius. No, it's not exactly what you want but it's more FF than FF15 was... easily.
