My favourite era for Final Fantasy.
VII One of my favourites. Great story, great music, great characters, absolutely kickass villain, very open system (battle, magic, summons, everything) which I loved.
VIII ****ing rocks. Easily my favourite in the series, best theme, best music, best story, best characters, best ending. And of course brought triple triad into my world.
IX Wen't back to the old style and dropped the techno-style of 7 and 8. It was different and I liked it. The story was a bit unmemorable but the gameplay made up for it. The last of the really great Final Fantasy's.
