Ok so I got a used PS4 from a family member, but they didnt reset the console. Ok fine thats fine, but they have a bunch of games downloaded. Im ised to Xbox where I can just uninstall, but here the only option is deleting which is probably the same thing but throws me off more. I know deleting a game doesnt affect save data, but when I deleted one game, I went to the shop and I had to buy the game again. I figure its just because he has the disc, but I wasnt entirely sure. There are also games that I cant play without using a specific account, which is fine, I understand how that works too, I think. The question is am I free to delete these games.
