FFXIII's a bit weird due to a lack of a proper International version, isn't it? The
FF Wiki says that there was an International version on 360 (which basically didn't exist in Japan) and a free update for the PS3 version of the game, which would presumably result in a lack of a meaningful bump from the International version.
FFXV's not going to get most of its sales from Japan, obviously, but I'll be really surprised if Squenix doesn't put out a separate FFXV Complete disc release internationally once they've finished updating the game, which should give it better future sales prospects than FFXIII (especially since its reputation is a lot better than FFXIII's). And then there's PC, which could also be a bigger factor if Tabata has his way and includes major graphical improvements... or if a healthy mod scene builds up around it and goes all KotOR2 on the "unfinished" content.
The reason SE has cooled their jets on international versions in Japan is because they began to sell much worse and because the changes they made for international releases are gradually diminished because of the close releases (IE, FF10 international features the English VO and the later added bosses, but FF13 they added no significant content). But in real terms: FF10 international didn't even add an extra 150k. It's just not as worthwhile to do the international versions any more, that's all. They also didn't make an enormous amount of money to begin with. I'm still not really sure what the deal was with the 360 rerelease, but I assume it was some sort of tie-up with MS Japan; MS paid a chunk of FF13's marketing budget worldwide.
I don't think FF15 will get an 'international' version but given the state they launched the game in and all the fixes they're making, I fully anticipate a rerelease before the end of the year. But like FF7 and FF10 international and even the markedly different FF12 International Zodiac Job System only sold 109,000. Basically: they're not significant. So, nah, it doesn't really impact the performance of FF13 in real terms, no. I don't think a 'complete' 15 release will shift much more in Japan than that either, especially since with patches there's
less incentive to buy now (whereas with 10, the only way to face the new bosses was to cough up over again).
I'm not too familiar with this stuff so genuine question here: the games mentioned didn't have DLC or any future content to look forward to.
So once the sale was made, that's it, which would probably explain the front heavy sales.
What with the future DLC and story patches being available soon, wouldn't these be a good incentive for both new and old players to keep investing in the game? And thus keep boosting up the sales steadily over time?
This way, 10 mil sales sounds possible.
That's just my take on it but not sure if it's applicable to the actual industry itself.
Tabata's talked about this, yeah. He wants FF games to have longer tails. With that said, tail tends to be less about DLC support typically in the industry. It doesn't tend to have an enormous impact. Mainly DLC seems to encourage people to not trade in/sell back rather than encourage people to buy in the first place.
FF15 has done really well, so it's not to be down on it, but I don't expect its sales drop-off to slow or level out, leave alone spike back up to any significant degree. The market has changed but not that much. I think it'll largely perform in line with the rest of the FF series in recent years. Those outliers with the enormous tails like Skyrim are, well, outliers.
