Yes, you can play your PS4 games on a PC without a PS4. You'll need to sign up for a service that streams PS4 games to your PC. The service normally costs $19.99 a month or you can pay a yearly fee of $99.99. This will allow you to stream PS4 games online and play them on your PC. You have a second option and that is through emulation. Play Station will also have a subscription where you can download titles from the site and play them on your PC. But once you stop paying the subscription the games will lock up until you pay again.
