MS took their foot off the gas halfway into the X360's life and then waited to step on it again in earnest until like... what, a couple of years ago? Its cost them at least two generations it feels like, and I'd argue they're still not at the level of development investment they should be at beyond the bandaid of the "everythings free!" approach of GamePass.
Sony was busy making a case for the PS4 all throughout the second half of the PS3's life. In its last year before the PS4 arrived, the PS3 enjoyed The Last Of Us, God Of War Ascension, Gran Turismo 6, Puppeteer, and Beyond Two Souls. Microsoft, for all the Phil Spencer talk, has failed to even approach that level of support for the Xbox One, and unpredictably is still lagging when it comes to console launches and being able to fill out an actual platforms worth of content.
