Square Enix might be pushing FF more and more because it gains more revenue than the other IPs do. That would be my explanation for that. Bravely Default is mostly critically acclaimed because its flavor and gameplay is much more in line with the classic Final Fantasy games (NES era mainly) than the Final Fantasy games we get now. I also hate the need for jaded, realistic FPSes, but I don't actually see gritty military shooters to be gaining popularity in the near future. Lots of gamers don't like how tired and done the genre is (not that they'll stop buying each and every game they complain about), quirky games like Stardew Valley and Undertale explode in popularity fast, Nintendo is still going strong and most of those toxic masculinity games don't last because they have to compete with Call of Duty.
