I saw recently that someone could see how much he played, eg Gta 69 hours etc. How do you see that?
I'm very sure that that is not possible. In any case, the PS4 itself can't display the game hours. BUT many games have an in-game function where you can see how long you have played it. For example in the statistics.
Just google where you can see how many hours you have in each game. If you can't find anything, this game won't work.
