A game that comes 3rd in the best games of all time list in Famitsu voted by readers doesn't have a "bad word of mouth".........oh but Famitsu doesn't count does it? Its very easy to say something has a bad word of mouth by looking at forums. And its mediocre according to you, amazing according to me and millions of other people.

If FF is a diminishing brand FF13 won't be very close to becoming the most successful FF in Europe since FF7, and in America it won't be close to becoming the 3rd best selling FF. Both things that it will achieve pretty soon that too with being on a lower userbase than PS2 was at and that horrible leona lewis marketing campaign which put people off. Now this isn't a sign of a game with bad word of mouth and a franchise of diminishing value. In Japan you can make the argument because its the lowest selling one since FF4 there, yet it ranks in the best games ever in a very popular magazine in Japan......clearly there is a large discrepancy between opinions on the game.

Next be sure to look at user reviews for FF13 and FF12 accross the net, you'll find the vast majority are positive. 

When you wanna see if a series is diminishing you need to analyze all of this, not forum posts, metacritic and personal opinion. 

The fact remains FFIX is still the lowest selling in the series since FF7.....when a main FF sells less than that we'll talk about it diminishing. FF won't be immune to decline if a truly bad FF is released, Tomb Raider, Crash Bandicoot and Sonic weren't immune to it either.....yet nothing like that has happened to the FF franchise so we can safely say its yet to have its, "Angel of darkness", "Whatever the first bad Crash Bandicoot and Sonic games were".

FFXIV may very well be the first FF with a bad word of mouth.....but even then its a MMO and things can be solved by updates and you just don't have a lot of FF fans caring for it.......many I know don't even know about its low reviews score, nor will they really care. We can't comment on this until a few months in and until we know the state of subscriptions the game has and whether people are sticking to it or leaving it.

Next I am not going to call the company that released FFXIII, DQIX, NIER and KH:BBS in one year going into the ground because its rare that I see such variety and excellence coming from a developer.

Last week Japan preview says that GT5 grow 20k preorders. 25k this week?

50 K this week 

I would give you an elaborate reply as to why FFXIII is crap and why it has a bad word of mouth. I would also give you a more elaborate reply as to why the FF brand is diminishing and SE as a whole is losing value and market mindshare. I won't though because from your post I can tell it wouldn't go anywhere, so I'll tell you the same thing I told the other dude, let's just agree to disagree here.
