Not much is currently known about the game play for Final Fantasy 7 Remake other than a trailer we were shown early in 2018. Since then development has slowed down with rumours of developers moving on from the company and also with Kingdom Hearts 3 close to being released not much is known about the future of the game.
However what we can see from the trailer below is that the game will be very similar to how Final Fantasy 15 was produced.
From what we can see below we will have full access to all the characters in the party and will be able to change in battle. Its interesting that we still see summons, magic and items in the fighting window..I do wonder how summons will work in this game!
Anyway when more information becomes available I will update this page with the details you need!
