"With backwards compatibility, it isn't something that we just think gamers might want," Tsunoda says. "We know. We're looking for and soliciting that feedback. It was the number one most requested feature for Xbox One by far."
Sony has no plans to match Microsoft in this respect, and the possibility of monetising those games through PlayStation Now makes it very unlikely that it ever will. For Microsoft, it's part of a broader view of gaming with Windows 10 at its core, which should, in theory, unite the previously disparate tendrils of Microsoft's sprawling organisation. PC and console, past and present, existing in harmony, each interacting with and complementing the other. Cross-Buy, Cross-Play, console to PC streaming; one might say that Microsoft should have been doing this for years already. According to Tsunoda, this is a first step.
"It's a really unique value that only we can offer. You still need very gamer-focused values, but there's lots of things you can do with our technology. We've really got a lot more going on [than our competitors]. We're doing things that can't be done on any other console.
"Letting people play games wherever they want, on whatever device they choose, and making that easy. Long term, that's really what we're trying to do as a platform."
