I understand what you're saying but I think the issue is bigger than this
First, turn based rpgs, even very simple ones, have no issue raking millions on mobile. Yeah yeah I'm basically killing my own argument by talking about mobile but despite this I don't think gaming is a bubble that should be limited to only certain platforms or periods. If Honkai Star Rail is making 100 milions in a month it's not just because Mihoyo is a big name it's also because people that play and pay for it find the turn based rpg gameplay interesting enough to spend money on it. In the end a game is a game: if a turn based game can be succesful on a platform why would they always fail on another?
Second, and this is the actual important part, how many truly exceptional "jrpgs" even released in the last years if not the last generations? Again I hate that I'm even talking about reception and awards but if we want to "target" the average gamer then you can't really ignore this issue: How many FF games actually won GOTYs? How many JRPGs were actually "flawless masterpieces" in the last 10 years? FFXIII and XV had tons of issue, Arise was one of the best selling Tales but would you call it a 10/10 game? DQXI is a very lovely title but is it really "amazing"? Hell even Persona 5: great style, nice music, but deep inside is it really so incredible? And obviously I'm only focusing on bigger budget releases but it's not like smaller titles, even ignoring the smaller budget, are faring much better (from Star Ocean, to Bravely and Octopath. From Trails, to Gust, or even to Neptunia, none of them are)
Now, about this last part, I actually have no issue enjoying these "JRPGs", just as I have no issue loving many other genres (hell one of my favorites is SRW which is lucky if it will ever review as well as SO6). Not every game needs to be GOTY, and in fact lots of games sold well enough without needing massive critical praise or without selling 20+ million copies. Which is why I'm going to go back to the second point and talk about "GOTY contenders". Games like TotK are GOTY contenders: lots of money was spent on it, both in development and in marketing. Same for Ragnarok, or HFW, or ER and many others. The problem is that only because you spend mony doesn't mean you will create a GOTY contender. Here's why we're now talking about the third part: SE thinks that by simply throwing money at problems they can sell well, except they end up spending money on the wrong things. Look at FFXV: why oh god why did it have a movie, an animated series, a tie-in mobile game, novels (multiple novels!)? But then you actually check and the game is only in
11 languages (of which only 5 have dubs)? Do you know how many languages supports HZD?
20 and 11 of them also have full dubs. Now this may sound like bullshit but listen to me: maybe, just maybe, mister "John Gamer" looks at certain things when deciding which games to buy? Language for example is the very first "accessibility issue" you can tackle. Some companies even realized this and prefer translating the in-game text in more languages than to add a single english dub. Hell I can count the amount of games I pay full price which are not in italian on my fingers (and the answer is one SRW30 but in that case I'm not so crazy to actually pretend to play it in italian considering it's a miracle it's even in the west). Games like Elden Ring, GTA, Super Mario and Pokemon are exceptions in the sense they can actually not have full dubs in every language they support and still sell 10/20 millions (or more speaking of GTA). Zelda wasn't that lucky, and guess what was the biggest change BotW brought to the series? Dubs.
Think I'm taking crazy pills?
Witcher 3 supports 18 languages and 9 dubs
Sonic Frontiers supports 12 languages and 6 dubs (and has supported them since Sonic Generations at least and yes I specifically picked a game that did not sell 10 millions and will never be a GOTY contender to prove the point that both text and voice translations are important regardless of the game scope)
ReMake 4 supports 13 languages and 9 dubs (and has supported them since RE6 at least)
Hell just take a random Sony, Microsoft, EA, Ubisoft or even Nintendo game. Even the Advance Wars remake is dubbed in 5 languages and that game will be lucky to sell a million worldwide!
I'm sure there can be many examples where I will be proven wrong (like Minecraft, or Animal Crossing) but the truth is if you want to actually reach the extended audiences then languages are the first thing to do. MHW supports more dubs than Rise and in the end it sold more. Coincidence? Maybe but I don't think so. Even Atlus realized this since one of the bigger points they made with the new P4 and 3 rereleases was the additions of more translations (and they also did it for the newly released EO HD trilogy). Even Konami knows it since
Suikoden I&II supports 8 languages, most of those new compared to the original releases.
And now let's go back to SE and why they suck at spending money: Forspoken costs 80 fucking euros and only
supports 4 dubs? I mean voice acting is the last of the game issues but if SE doesn't trust the game enough to spend more money on voices why would I trust in them spending more money to make the game better? This is the issue with JRPGs, especially SE ones: despite somehow spending millions on them the end product still fells very cheap: empty areas, bad story, subpar voice acting, little to no side content. But... but look at this amazing 1:25 minutes FMV that takes 20 GB in space, isn't it amazing! Look at the lifelike expressions! Who cares if the actual in-game models look like Oblivion potatoes. Gamers might me stupid but even them can smell the lack of substance. At this point I may as well spend half (or 1/4) of the money and just play a Tales, or a Trails. Those games have obvious budget issue but at least they don't try to pretend to be the best thing ever made
Maybe one day a better company will actually take the challenge and release a true JRPG Goty, but until that happens a blanket statement that turn based games can't sell will always ring hollow, just as a blanket statement saying SRW will never release in the west because of licence issues and low sales potential was proven wrong
