Yes. You get access to a bunch of games for the PS3, Vita and PS4 for the duration of your subscription. Some of them rotate in and out monthly though so you have to add them to your account to ensure you can always download them. I've received so many good games from Plus that I've lost count, its a ridiculous bargain.
Makes XBL look like absolute trash by comparison.
