PlayStation Plus used to be an incentive-based subscription before going to a multiplayer requirement in the current generation. Back then, sales and deals were plentiful and while discounts still exist, there is now a sale that purely benefits Plus members. There are about seventeen games on sale at the store that are heavily discounted for Plus members. The games can be viewed here. The games include discounts for the likes of For Honor, Mafia III, Elder Scrolls V: Skyrim Special Edition, and more. Head over to the site and see if there is anything worth jumping on.
