The thing is, calling these "exclusives" is something if a misnomer in my opinion. Console exclusives are proper exclusives since you need the physical hardware in order to play them. The same goes for Netflix or Amazon exclusives, since you need to pay for the service in order to watch them. But for PC "exclusives" you only need to download a free launcher - and in that case, are they actually exclusives? If PS4 gamers could legally play XBox One exclusives by installing a free piece of software (and vice versa), then the concept of console exclusivity would go out the window. The same goes for Netflix or Hulu - if you could download a free and legal piece of software and watch exclusives on the other service then there's no point in calling the shows exclusives. The same should apply for the PC - if there is no physical or financial barrier to playing the games, then what's the point in calling them exclusives?
