FFX-2 wasn't such a bad game so long as you absolutely did not try to think of it as a true installment of the FF series and rather as fan service galore for all the appeal that fans had for the female characters in FFX...

Square-Enix will continue to churn out FF games and have storyboards going years in advance before the games even go to model. They already knew what FF9 was going to be about when FF7 launched, it's how Japanese business works. They look WAY further into the long term than other countries do in terms of business (50 years in some industries). FF games make money, they have for over 2 decades now, and probably will for another 2 decades.

I enjoy the remakes and the spin-offs, mostly because I don't expect to be amazed the way I was when I first sat down with FF7 and played through it. It's all about expectations... Don't think that just because it has the FF label that it's going to be groundbreaking. Just expect to be entertained =p
