First of all, I want to say that I am a FF myself, fell in love with the game back in 1990 with FF 1 on the NES, played and loved all of them expect for FF 3 & 11 (didn't play both). I don't know if it's this site that has a lot of FF fans but during the week FF XIII was released, the majority of the threads have been about the game and they all got a quite numbers of "posts". Beside Halo 3, I don't remember a game having so much thread about it on its release week on this site.
I have been going to this site for the past 2 years and FF fans are not shy at all to show their loves for the game. Even with all those bad reviews (I think this is the FF that has had the worst reviews), the fans still didn't care and would still bought the game day one. And one thing I am pretty sure about, when those fans were buying their PS3, one of their main reason was for FF XIII (that is my reason for buying a PS3 too, although I am enjoying a lot of other games on the system)
So to all FF fans, you guys are probably one of the greastest fans in the world, because bad reviews didn't stop you from playing the games. I am pretty sure even if well known reviewers had talked trash about the game, you would still buy it day one.
