So, they're just turning the Xbox one into a Windows 10 PC, in a way?

As a PC gamer, I'm all for letting Xbox games coming to PC - and any system designed to do so is welcomed. However, if they do, then what's the point of owning an Xbox? I can understand the people that just want a box to shove under their TV that will play games, but what about the people that will play on what gives them the best experience? The Xbone is already known to be an expensive low-tier PC. If a person, who wants to make sure that they have the game in the best way possible, knows that they have the choice between a $500 Xbone that will run it okay, or a $500 PC that will run it a lot better, they're more likely to get the PC. It was happening towards the end of the last gen's cycle, and it will happen more now if people know that PC is the better bet.

Exclusives were the last thing that made people buy Xboxes. If all games were available on both systems, most people would choose the system that would run them better and would have better features, which, right now, is the PS4. Now, if PC can run Xbox exclusives, a lot of people aren't going to go from the 360 to the One, they're going to go to PC; because PC is going to give them a better experience, without forcing them to never play an Xbox only franchise again.
