I'm a little confused here. I haven't read every single one of the thread's posts in their entirely, but...
From what I can tell, the situation is this:
Microsoft wants a bigger slice of the pie when it comes to Japanese games.
Microsoft currently owns two gaming platforms: The Xbox One and the Windows-based PC.
Out of those two platforms, the PC is easier to code for and has a much larger install base in Japan.
But rather than cutting its losses with the Xbone in Japan and focusing its efforts on getting even more Japanese devs to make games for the PC (games which would often be playable even on mid-range hardware because of their relative graphical simplicity), Microsoft is still trying to push the Xbone towards becoming a player in the Japanese gaming scene.
Am I understanding this correctly? Am I missing something that's incredibly obvious? Because it seems to me that Microsoft is not using its resources wisely.
