Hello, I am new to the PS4 community, this is my first home console in a long time. I have bought this machine used, and the previous user still has his account on it, with several games installed. Will I be able to keep the games on there, and what should I do with them in order to keep them? Or are the games linked to an online account? I am currently not connected to the internet yet. I would also like to know whats currently possible on firmware 3.5, thanks!
