7 followed closely by 6. And then 9.
Bonus: For FFXVI.. A more streamlined and focused FF. Don't want a massive empty open world to explore and waste time in. Keep the overworld and semi-open world like previous FF. And have a more immediate path and story.
Gameplay wise.. I'm hoping an evolution of XV and FFVII Remake. And playing more like Kingdom Hearts. Keep it tight, make it gamey if need be. Bigger parties would be great too.
