I like SE's desire to explore how to do "fantasy" in different types of settings, but I do think it's time the series tries its hand again at a more traditional medieval fantasy type of game.

Personally, I'd like to see XV as a serious game (including reflecting XIII's effort at more realistic-looking humans and creatures as opposed to IX's emphasis on anime-ish caricatures), set in a medieval fantasy-style world and taking the old job classes out for a spin using modern technology: black mage cults in their blue robes and witch's hats, white mages in their white robes with red-slashed sleeves, armored knights, ninjas with throwing stars, red mages with cavalier hats, air"ships", blue magic, the old summons including Ramuh, Ifrit, and Leviathan...

I wouldn't want a retread of the old job systems, but come up with something that suits the modern gaming experience using the traditional job designs.

Hardware has advanced a ton since the days of IX, and especially the I-V era, and it would be nice to see how a medieval fantasy world would turn out in modern hi-def.

(As an aside, I'd also like to see SE try to make a futuristic FF that didn't take itself so seriously)
