I don't think it can be emphasised just how negatively some people react to JRPG storytelling, or anything too "animey" in general. I think the reason why overtly Japanese franchises like Final Fantasy achieved the massive mainstream status they still hold today is because in the PS1 days they were the only game in town, with Western devs lagging far behind in terms of cinematic story-heavy console game development.

Now that the industry is dominated by titles developed both by and for Westerners, the average gamer has no reason to bother with games where cartoon teenagers with stupid names and even stupider hair yap about nonsense for hours when they can just play whatever CD Projekt Red or Bethesda game is out. This is not to say that Japanese games don't have a large fanbase in the West, they definitely do! They just don't have the same kind of broad appeal
