Physical PlayStation 4 games
"Code in a box": a physical case or sleeve that doesn't contain the game, only a code to download it in full from the digital store. It's indistinguishable from a real physical edition until you open it. Here we split the two apart for PlayStation 4.
Full physical: the game is on the disc (51)
No mandatory extra download (beyond patches). Works offline as soon as you have it in hand.
Code in a box only (2)
The box includes a code, but the game itself takes up the same space and needs the same connection as the digital version.
