It's the most critically acclaimed FF on GameRankings

PS1 started gaming? i thought it was 360... my bad.

Don't be sad... maybe Final Fantasy XIII will win an Oscar this Sunday

FF Anthology (FF5+FF6 PS1 port) scored 80 on metacritic. Does that count? lol.

Btw how the hell does FF Anthology score only 80 when the SNES version of FF6 scores 90+% on GameRankings? I understand that the SNES graphics are primitive by late gen PS1 standards but I don't think graphics should factor in too much with the overall score (and yes I know Anthology includes FF5 too but in terms of FF fan opinion, it's not like FF5 was the black sheep of the series. It's story was lackluster and some didn't like the job system but it was still a well-respected FF).

Ok, yeah that's a bit too misleading of a title, you can't just say "worst meta score since VI" and then say "yeah there are no meta scores for VI" it's already tricked people like severance

Worth noting http://www.metacritic.com/games/platforms/gba/finalfantasy6advance?q=final%20fantasy the GBA port of VI since it's the only version that's released since meta started tracking reviews, it has VI at a 92, so again deceptive title, but if you wanted to be honest it'd be the lowest since XI or if you feel that isn't "main line" enough for you you can pick out III on the DS, but those won't net you as many hits I'm guessing

Anyway... ~locking~

Final Fantasy VI Advance got 92 on Meta

And that's for a 13-year-old game.
