Sony’s investment in Gaikai is finally paying off for gamers as the PlayStation Now service is readily available on the PlayStation Network. Granted, the program is in its beta form at this time, but you can now stream some of your favorite PlayStation 3 games to your PS4... for a fee of course.
There are more than 100 titles available at the moment, with different rental options. I have to be honest though, they are all pretty expensive. Rental terms vary from a few hours up to 90 days, with the 90-day rentals costing as much, if not more, than you can but many of the games for at retail. Sony intends on addressing this in the near future and the pricing system is far from final.
