The problem X-box has is that they just cannot get exclusives from Japanese developers. Which leaves them with Western developers, who Sony is also after.
yeah.
but with such small Xbox sales in Japan, who can blame J Devs for not wanting to support Xbox? And, for J Dev games that are multiplat and on Xbox, I'm sure if you breakdown the sales, the games most likely sell more on PS4/Switch than on Xbox.
so J Devs aren't willing to support Xbox because of the limited Xbox userbase for J Dev games. which means less J Dev games get released for Xbox, which in turn contributes to the small Xbox userbase for those kind of games.
so it's like a vicious Catch-22 cycle, if that's the right term to use.
bigger Japanese companies like Capcom and Namco Bandai tend to support Xbox ( except for Street Fighter V ) but even with their titles, I'm sure Xbox is the smallest userbase.
Xbox is making progress on this front, but it still can't compare to the competition.
And another thing I learned recently, with games like Soul Calibur VI, even if a J Dev game does go multiplat and go to Xbox, most likely the PS4 will be the lead/main platform. which can result in the Xbox version feeling less optimized.
In Soul Calibur VI at launch, I remember the Xbox version had greater menu/navigation lag and the menu background audio was much softer compared to the PS4 version. They eventually patched those issues on Xbox, but it was still less than ideal and optimized at launch.
The exception to this, however, would be Dead or Alive 6. Somehow, the X1X version was able to secure exclusive rights to HDR support. Even the PS4 Pro didn't get HDR, which was kind of weird since it should be more than capable of supporting HDR.
