Yeah there was :) You had to go through time to complete the game. And you had to fight one of the feinds on a space ship. The game didn't look sci-fi but it did have sci-fi.
As almost all of them have.
I prefer the post apocalyptic industrial slum thing and steam punk of FF6/7 over FF1-4's mix'n'match game. Games more recent than 7 I won't comment on as I didn't like them so my opinion is negatively biased and that's usually unwelcome and unnecissary. But adding technology in a more mainstream sense to the plot has never ruined a FF game in its own right. I'm sure there will be plenty of fantasy about it. The game looks to be more interesting and faster paced than 8-10 were (to me anyway).
