I'd get over it pretty quickly really. Quality Final Fantasy titles have been few and far between for the last near 15 years now. During that time TV shows have come and gone as have other games. Until a release date for XV is actually confirmed - the series is already pretty dead in my eyes, all these mobile spin-offs/remakes just feel like an anti-climatic swan song really.

Of course I'd be sad at first, just like I was sad when some of my favourite TV shows ended. But like good TV shows, some of the better FF games have little nuances you don't notice until years later. FF would probably become something of a distant friend, that you had fond memories of but drifted apart as you both got older.

If you'd asked me this back during those 6-8 years when FFVI - X came out almost like rapid fire, then I'd probably say I'd be upset. But these days FF titles take far too long to show up that I've usually lost interest until the pre-release marketting starts kicking in.
