Can you attempt to quantify this effort in comparison to other game consoles? I'm not very familiar with the Xbox scene, but I would assume that there was a lot less drive to achieve this given that Xbox has never really had many big exclusive titles and remains the least popular major console (with an abysmally tiny market presence outside of the US).
As an aside, I wonder if Microsoft's extra effort into securing the platform comes from their tighter partnership with media distributors/streaming platforms and their off-and-on demonstrated desire to position the Xbox as a home media center more than just a gaming console.
