KH3 and FF15 launched on both at the same time. FF16 is the exception money hated timed exclusive, we don't know if KH4 will be the same, but Disney would probably have a say in the matter.
FFXIII and FFXV are the only two numbered Final Fantasy games to launch on Xbox.
Kingdom Hearts 3 is the only KH game period to launch on Xbox. Dragon Quest never has.
There's no benefit in acting like Xbox gets access to Japanese games, especially RPGs like PlayStation or Nintendo does. You won't fool anyone.
It's hit or miss, at best. And even those that do eventually come to Xbox, like Nier Automata, Persona, etc, come much later. Others like Atelier, most Tales games, Disgaea, etc never come at all.
Xbox fans are mostly fine with that, as their focus is on shooters, sports, or "YouTube games" such as Minecraft and Roblox.
It's no different than Switch fans not caring they don't get Call of Duty or Battlefield.
There are different audiences on these platforms. Those of us who want everything have all the consoles.
