There's a poll going on over at GameFAQS right now between FFVI and FFVII on the main page. About 15,000 votes cast and only 31 votes difference as of posting this!
Poll is here http://www.gamefaqs.com/poll/5728-all-of-the-other-final-fantasy-games-aside-which-is-better-vi-or-vii
I'd like to see what popularity it has over here, see if we get similar results.
I'm only going to give the option for each game, or an undecided/don't care option.
Let the voting begin!
