My pick for a FF character at this point would be Yuna, but yeah if we somehow get a third one it's probably going to be FFVII again. I'm 90% sure it would be Tifa. The only other choice I see is Terra from FFVI.
Not that I'd complain with Tifa, she's ****ing great and badass, but I'm more a fan of Yuna and Terra if we speak about FF girls.
You say that as if Japanese AAA development wasn't also aimed at Western audiences as much as, if not more than, their local gamers. Final Fantasy, Resident Evil, even Sonic are all more popular with Western audiences and they're their respective developers' biggest cash cows.
With how expensive AAA development has become it's completely unviable for a big game to appeal solely to the Japanese market, whereas tastes in the Western world are uniform enough that it functions as a single, massive and very lucrative market.
Give credit to Sony, theirs is the only console that has both computing power to run big and ambitious games and an audience willing to play Japanese games. They get flack for being all gritty and cinematic games but the PS4 is the console that turned Persona and NieR into household names.
Granted, dumb **** like removing the X-O swap in Japan can alienate audiences and they do need to put in the work to reassure people that they haven't ditched the market as a focus. But to want for them to fail can only hurt gaming as it is, because it's not like Final Fantasy XVI can exist on the Switch or sell well on the Xbox Series X. The alternative is that you just don't have those kinds of games.
Not to say, "Western AAA games" isn't exclusive of them. I mean... most multiplatform games from the biggest third party companies are precisely that. That's why I will never understand why people complain about Sony's library of games. Obviously, their games won't appeal to everyone, but that could be said about any company, including Nintendo. And generalize isn't helpful, I've seen people here define Sony's games as "third person movies" and similar descriptions, and that's just dumb. Some people do the same with Nintendo, saying they only do "colourful games for kids" and I think everyone here agrees that's obviously a stupid simplification.
And the flack you mention is mostly from a minority of people. Not the same situation but this reminds me of when Sword and Shield came out, and some people actually believed no one was going to buy it, or that very few people were happy or okay with the game. We all know the result and how well the game sold.
That's the most effective way to make a company know what you think. With your money. If they see that they're selling incredibly well they're not going to listen to the few people complaining on Twitter. Because yeah, in the grand scheme of things those people are a small part of their audience.
People complain about them basically shutting down Japan Studios (and I get why) but at the same time, most of their games if not all of them had mediocre sales at best, according to their expectations. People on the internet can cry as much as they want about "we're not getting Gravity Rush 3, **** them!!" which yeah, sucks, but if very few people bought the previous games, that's what you get. And I love some of the IPs Japan Studios worked on, but not gonna lie, I kinda feel some people really never cared about them until Sony closed them, and this is just another dart for them to throw at Sony, because before I never saw them talk about Gravity Rush, the Team ICO IPs, Legend of Dragoon, Puppeteer, Patapon or Ape Escape.
This isn't really different to how Nintendo has handled some of their IPs. F-Zero, Advance Wars, Golden Sun, etc. have fans asking for new games, but it's easy to ask for new games. If they wanna make a difference they will have to actually buy those games (if we get new ones) to show them that people are really interested in those series.
Sony has found their niche in the industry, and that niche is single player games with big stories and great visuals, and said niche of the market has granted them better sales than ever software wise, a ton of awards and prizes for a lot of their games, while the PS4 breaks records and being the fourth best selling console of all time as of now. And the PS5 is so far doing better than the PS4, and considering we're in a pandemic, that's impressive.
That doesn't mean they don't have other things. Everyone associates Nintendo with platformers or with fun games that are aimed at all audiences (which could be considered Nintendo's niche in the market), but that doesn't mean you won't get different products from them, because games such as Famicom Detective Club or Astral Chain are clearly different from Mario or Kirby.
