Hey boomstickbhg – With PS Now, you can rent by title for specific games, or you can choose a subscription that delivers additional value with a wide variety of genres. For example, you can try out a game by rental first, before deciding to actually purchase the full game and download it to your console. We believe this streaming game service will add tons of value to dedicated game consoles in addition to packaged and downloaded games, and in doing so, we will open up a new world of possibilities across PlayStation platforms.
Of course, one of the big reasons we are offering a closed beta is to get feedback on all aspects of the service, including of course the experience with rentals and subscriptions, so we look forward to hearing more feedback from our community as we move through the beta.
