Brave Exvius might be Final Fantasy XVI. We have a protagonist with a meteorological name: Rain. Within the story, Final Fantasy: Brave Exvius boasts:
“Let a new tale of crystals and heroes begin!”
harking back to the Fabula Nova Crystallis series (of which it may very well belong to). With the success of World of Final Fantasy, who’s to say we won’t recruit characters from other Final Fantasy games? I also think we’ll see more of Agnis as an actual strong female protagonist working alongside Rain, Lasswell, Fina, Lid. Rejoice if a game like this comes to pass with HD graphics on Agni’s engine. It’ll most likely be turn based.
Most likely, Final Fantasy XVI will take place in another medieval world. But I would personally like to see a very ancient style world. Medieval isn’t the only type of fantasy setting one can do. Go ancient. It would be like our world, only from the distant past. Make a Roman-esque empire in a world with barbarians, tribesmen, etc mimicking the ancient cultures of past eras. This is seemingly when cultures had an abundance of mythology. In their world, the myths are real. Maybe we’ll have to defeat gods of the myth. This would explain the lack of gods in the modern world. Maybe it would raise a debate as to whether defeating them was right. And of course, every era would have their own crystal.
But the pendulum swings both ways, and when it goes too far one way, it always moves back. Final Fantasy XVII will probably then be futuristic to compensate. Maybe they might revamp the story of Final Fantasy: The Spirits Within to become playable. Or, we may actually go through different characters from that universe. And they would go through similar events parallel to the story (similar to Kingsglaive).
Regardless, I would like to see an ultra-futuristic setting. Nothing like Final Fantasy XIII; I want them to go even farther into the future. I would like them to look to Star Trek, rather than Star Wars, for inspiration on the setting and technology. And instead of gods, we fight extraterrestrial aliens. But then, by fighting the aliens, would our characters upset the natural order of the universe? Would they play right into the villain’s hands? And of course, each planet would house a crystal at the center. Maybe even an ultimate crystal at the center of the universe.
Still, this might be a little bit too far away from the Final Fantasy mythos.
