I don't think you'll hear a lot of debate about FF6, but FF8 and FF12... Well, FF8 could have been great, in my book, if not for one little thing: they obviously didn't finish play-testing it since it's insanely tedious to draw magic or collect items for refining, and since the level-up system is about as refined as your typical RM2K3 custom battle engine is (ie. not very). FF12... I just plain hate. There's nothing about it that can redeem it for me. Which is funny, because I liked the demo of FF12 quite a bit, but the final game just turned out to be a grind sandwich...
