I don't like buying games off PSN that I can get on Disc as you technically don't "own" the game. You "own" the "license" to download on your console and it can be revoked at anytime for any reason.
But I have bought Psychonauts and Primal for my PS4, with their "updated graphics".
Over just current gen consoles (PS4 & XB1) Around 150-200 mark.
Prefer digital as a. they're cheaper (If you get psn card & game share with someone else) b. Don't have to queue for the game c. don't have to get up every hour to change disk
