Final Fantasy is still doing the exact same thing they've always been doing, but unfortunately game development means it takes a decade before you'll get your next mainline game now.
If you didn't like 13, don't worry, 14 will launch in 3 years. Nevermind, 14 was a disaster and had an in-universe reset as a result three years after that... oh, you don't like MMOs anyways? Don't worry though, in another three years you'll finally get 15! Oh, didn't like 15 either? 16 will be your game, trust me, just wait 7 years. Wait, you don't like 16 either? Fine, in 2033 we got you with 17, trust me.
at least back in the ps1 and ps2 days if you didn't like that specific FF game, maybe the next one in one or two years would get you. I can find forum posts from back when 7 dropped and there were people doomposting about how it didn't feel like FF anymore because of how different it was to the first six games. If only they were psychic and could see 9 was coming in a few years specifically as a throwback to that era lol.
