All First Party XBOX Games Coming to PC!

In a recent interview with GameReactor, Head of XBox, Phil Spencer confirmed that all first party games will be coming to PC:

I don't think its healthy where for every first-party game that comes out I have to get the question, is that coming to Switch or is that coming to Switch, and it not because, I love Nintendo and our relationship with what we are doing, that want us to be all in or not, and there is this expectation from customers like there is now on PC, where people don't really question - there might be some timing things, on when certain things happen - but if we are shipping a first-party game it's coming to PC. If we are shipping a first-party game on PC it's coming to Steam and our own store. Like we built an expectation from our customers.

This is great news for PC gamers as they will no longer have to decide if it's worth it to purchase an XBox console to play certain games.  Microsoft Studios makes some great games and it's awesome PC gamers will be able to play them on the console of their choice using the settings and options we've grown accustomed to on PC.
