Im sure those otakus wouldn't mind being stuck in an RPG. 

The PS2, was still selling on 2008-2010, Selling at a High rate, also had a unusual Life-time of Sales, The Market isn't in such a Decline, in those Researchs they use the Handheld Market, together with the Home Console market, and this Generation is  over 30 Millions behind the last generation only with the Japan Numbers.

France, was over 25% Bigger than Germany, last gen, now Germany is 6-8% Bigger than France, this means that  France's Console Market  is in Decline ?.

Also, those researchs only track Physical Sales, isn't fair to compare Physical units sold of 2014, with the ones of the 90s, the Gameboy, alone was selling better than Nintendo 3DS + PS Vita, on Japan, they don't track Digital Sales, so the Market can still be Flat, instead of Down, with the Digital Sales, and would not be Down, if was not counting the Handheld market.

A Market that Sells Dozens of thousands of Software per week isn't a dead Market, and never will decline this much to became a "Dead market", is the Second best selling market for the Wii U, and the third best selling market for the Playstation 4.

FF XII is at 2.33 Millions according to VGC.

Well think is the keyword we don't really know. But I see that the biggest Western games are GTAV and COD Bo III on PS4 (correct me if I am wrong). And those games sold around 300K each on PS4 so how many PS4 were sold? 300K is to optimistic and my guess would be 100K?  And less than 5% of PS4's sold are because of those Western games?

But yeah that's exactly what i meant. We would all have suspected a better performance for MGSV no?

And how many PS4's do you think are sold because of those Western Games. 

A better question would be how long the PS4 will remain above the PS3 launch aligned.
Declining interest in consoles would be devastating...if this was the PS3, but its the PS4 in a completely different generation with a generally more favorable environment sans console interest such as lack of competitor (atm), lower price, etc...

If the generation is much shorter as many alleged, then practically every other concern gets overshadowed by time frame, and this question simply devolves into a resounding (virtually) one sided no.

The Zodiac Job System, is a Japan exclusive, Final Fantasy games had those Exclusive content for Japan,  Final Fantasy 7, had a Director's Cut, but it was with the Original game, Final Fantasy 8, had a Add-on, but Final Fantasy 10, had a "International version" exclusive for japan, with Dark Aeons, and with the Super Boss Peneace, Final Fantasy 12, Had the "Zodiac Job System", those Versions sold Hundreds of thousands units on Japan, and even who don't had purchased the game, was able to purchase those editions.

Split the sales of those 2 versions is like make BloodBorne, and BloodBorne Goty Edition, because are "Different versions", but i made a Mistake and i took the Revenant Wings's Sales.

Final Fantasy 12, sold 2.44 Millions on japan acording to VG Chartz, i have 100% of Confidence that Final Fantasy XV, will break Final Fantasy 13's numbers, and i also think that can break Final Fantasy Xii's Numbers.

But FFX's numbers are right, without the Remaster, and just with the Original game, and the Japanese exclusive version, it sold 3 Millions of units on Japan, Final Fantasy, and Dragon Quest, are bigger than Mario Kart, on Japan.

The Division, sold more than 100k on the first week, Raibow Six Siege, i think that it already  sold more than 100k on Japan, Just Cause, i think that sold more than 50k, if i can remember, The Witcher 3, sold 143 Thousands, Star Wars Battlefront, over 175 Thousands, Fallout 4, 175.3 thousands, Battlefield Hardline 112 Thousands, Batman Arkhan Knight, 76 Thousands, Far Cry 4, 64 Thousands, Assasin's Creed Sindicate, 55 Thousands, Dying Light 53 Thousands.

And you are counting 2 games as 1, the Crowd for a Open sand-box Western game, is different than the crowd for a Competitive shooter game, those 2 games, in Japan the GTA V, on PS3, nearly sold 1 Million nof copies according to VGChartz, so out there are a Lot of japanese people that like Western Games, not just 100k, people will purchase the Machine with most games, if Wii U, had Third Party support, it would be selling more than it is now.

Saying that only 100k of the PS4 Sold in Japan was because of Western games, is not true, actually more people purchased Playstaiton, for Western games than before, the reason Why PS4, sells more than Xbox One, on Japan, is because Xbox, only have Western games, but the Playstation 4, have the Japanese, and the western games.

I only combined them because I didn't want to make guesses how many consoles are sold based on each of  those two games. When most Western games releases they don't create a significant bump in sales.  All we have is facts and that Western games account around 10% of the video game sales in Japan. So you make a fair guess and say that 10% of the consoles sales are because of Western Games. I just believe that most Japanese gamers got a PS4 and then later bought a Western Game for their console. So that 10% would be lower but even if it is 10% or what 250K of the PS4 sales? I would not consider that high but low but you are free to think otherwise.

We are not talking about Japan's Market, just the Western Game sales  for Consoles on Japan, Wii U, don't have a single western game besides Assassin's Creed, Xbox One, is little to no Existence on Japan, so you need to take the Playstation 4 numbers, throw away Handheld, Wii U, and other numbers, they don't have Western games on it, so is impossible to track something that don't exist.

On 2015, The Top 10 Best Selling Playstation 4 tittles, 4  from the 10 was Western Tittles, with 1 of them  on the top 5, and the other on the top 3.

On the top 20 best selling Playstation 4 games of 2015, 10 of the 20 are Western Tittles, so Saying that only 10% of the Consoles sales of Software on Japan, are Western Games, this isn't true, The Western games are big, like  some Japanese games, the Difference is that on Japan, the Japanese games  Sells so much that they Chart, they also have a lot of Japanese Exclusive games that launch much time later, or even don't launch out of Japan, on other countries Japanese games don't even Chart, but also, Japan's Wester games sales on consoles, are bigger than a Lot of Western Countries on Gaming.
