It's a good time to be a PS4 owner who appreciates a good deal. That's because Sony has launched a new line of low-priced modern classics called PlayStation Hits. Just like the Greatest Hits and Essentials lines from Sony's previous consoles, PlayStation Hits keeps these older PS4 games in print and lowers the price to $20/£16/€20. Those in the US and Canada can buy the lineup of PlayStation Hits now on disc or on the PlayStation Store. The UK/Europe market will have to wait until July 18.

The actual games available as PlayStation Hits vary by region. Those in the US can get games like Bloodborne, The Last of Us Remastered, and Metal Gear Solid V: The Definitive Experience for $20 each. Different groups of games--though with much overlap--are available in Canada and Europe.
