Why why why are you still banging that "but is less than XIII" drum at this point? That is irrelevant in this new landscape and just makes you sound so desperate to steer it towards a narrative. It's obnoxious.
First off - Sales aren't everything, as in my opinion two of the best FFs and my personal favourite (12 and my favourite, 9) are two of the worst selling ones. Sales are still an interesting datapoint though.
To answer the question - cos, er, comparisons are interesting, and fascinating. I've been noting by how much it's been beating 13 in (most) Western territories, too - it paints an interesting picture of the market in itself. For instance: the chasm of difference in Japan
is going to have a deep impact on FF16, as they now have an interesting choice: They can focus in on the West even harder (which is what I think they'll do, with an art style that resembles Kingsglaive more and so on) or they can try to find ways to reinvigorate that market in Japan. This is a challenge for all market-leading brands - for FF, for DQ, for Resident Evil, for Sony Studios Japan - in that market. So it's
important.
FF15 is a success. I don't think anybody's disputing that, obviously. The situation in Japan is interesting both on a series granularity level and a broader market level, however. Even if we want to place the shift solely on the market (though I reiterate: FF15's decline is a large game-on-game percentage decline than the
average for the collapsing Japanese market, indicating there is probably another factor (the open-world, Western-esque design of the game, I think), that in itself has fascinating and major implications for the FF series going forwards. I mentioned Resident Evil earlier; that's a series that throughout its lifetime grew to be more and more Western-focused until we have the most recent entry; made in Japan but with enormous Western focus... Released in the West first, with a Western lead writer, with the Western voice cast used for performance capture
first and then the game localized back into Japanese. See also Kojima's work. If FF's sales base skews heavily off towards the West, it will
change the approach to future entries, and that's fascinating and supremely interesting.
So, yes -- it bears investigating, it bears repeating, it bears discussing. Let's not act like on the last page alone I didn't: 1) state, unequivocally, that "the franchise decline is a myth", 2) post the US sales figures and call them very good, noting how it will wipe out much of the Japanese decline, 3) talk about how "it'll largely perform in line with the rest of the FF series".
Like, if this is trolling, you really need to grow a pair, innit.
Germany has never been a particularly strong territory for JRPGs (in Europe, France has always absolutely dominated) but the performance of FF15 there has done seriously well b JRPG standards and is like 30-40% up on previous entries. It's a small dent in the international sales obviously because it's a small market, but the growth is very encouraging and can probably be attributed to the game having a more WRPG-like feel, at least in the open world half.
2009 isn't 2017. The console market and the demand for JRPGs moved West. Moreover, I'd argue that overall sales may be misleading (leaving aside the digital sales figures). What's important is revenue. I think a more accurate picture of the overall health of the FF series will be the long-tail sales of the game -- the DLC and SE's implementation of a GaaS model. We'll see what happens at the end of this quarter when SE posts their financials.
There are important comparisons to make about audience size, because even in a GAS model you want to obviously have the largest possible audience to work with. Activision knew they were going to make money hand-over-fist after the fact with Destiny, but they still needed to sell 10 million at the top to really have the base in which to make the revenue they projected. You're right too, of course - revenue makes an enormous difference. The FF15 stuff is experimentation, but I firmly believe FF16 will slide more into the Games as Service model in a sort of Borderlands, Destiny, Division direction, and so that's going to be a major future bullet point for the series - an attempt to find a middle ground between the MMO FF and the SP FF, built by a mixture of people with experience in both camps. (As an aside: this is what a lot of RPG studios are doing; Bioware's new IP for 2018 is also this kind of game.)
