Finally, these are all Cross-Buy games, meaning if you buy it once, you’ll be able to download it for free on any available system. Oh, and one more thing: if you have purchased these games previously on PlayStation Store, they will be available to you when they release on PS4 or PS Vita at no additional charge.
