The PS4 and the PS4 Pro are the exact same system. The pro is a more powerful version of the PS4, but the bottom line is that it is the exact same thing. There are no games exclusive for the Pro. This means that all game discs for the Playstation 4 will work in either system. In some cases, the PS4 Pro will offer improved resolution, frame rate or other visual improvement over the standard version of the game. You will not need to purchase an extra copy of the game to do this, the same game disc will work for any PS4 system.
