Let's face it. We have three major competitors, and they all want our money. And what makes one stand out from the rest... EXCLUSIVES! If a title is released on both the Xbox One and the PC, then it's exclusive to Microsoft. So Microsoft reaps the benefit whether the title is bought on the One or a Window based PC. The same with Sony with Persona 5 being released on the PS4 and the PS3. And we've had titles to be released on both the PS4 and the PC. If one can make the argument that "Why do I need an Xbox One when I can play it on the PC?", why can't the same be argued against the PS4 when that game is also on the PC? The exclusivity, I think, refers more to the competing company rather than the hardware itself.
