It was rushed out to capitalize on FF7's popularity
and was reduced from eight quests to seven because they didn't have time to finish the eighth. I've written about it here: it's a wonderful open-world game with an inventive combat system. Rich Bunnell called it a "broken game", which is pretty accurate (there's a trick that can be done by everyone that gives you infinite money) but it's a lot of fun. If you're into RPG gameplay more than the story (basically, if you liked the jobs systems in FF5 and FF3, or if you like playing with different lineups to match up physically or magically, etc.) it's a really good game.
I think a lot of people were expecting (a) something like Final Fantasy VII; and (b) a game that gave you a clue where to go next and wouldn't get you lost in a big open world, going on independent of your quest. I guess (c) a game that's not broken. It's not for everyone.
