The beta of PS Now has started to charge for rentals and the prices are currently no cheaper than to buy the games second-hand.
Cloud gaming service PlayStation Now has moved into the second stage of its beta trial in the UK, as Sony try out various pricing systems to stream and play games.
PS Now allows you to stream PlayStation 3 games direct to your console (and others devices) without needing to download them. It uses the Gaikai streaming tech that Sony bought a few years ago, with the ultimate aim being to also offer PlayStation 4, 2, and one games.
