I think most of the FF games ended perfectly wrapped up and dont need a sequel. VII definitly left the door open for it. VI... I dont see the fun in that without magic, as much as I'd love to see what the party is up to, I'd rather see a prequel about the War of the Magi. That can be expanded on so much, and I think it'd be rather fun.

For IV... isnt Golbez just going to sleep on the Moon, same as FuSoYa? Didnt the say that as they left? I cant remember... Regardless, I wouldnt be much interested in a IV sequel.
