I believe that an addiction best describes it exactly the way it is because there isn't anything that's going to be making them do that if it's not addiction.
Yeah, it's something that most people find to be very challenging for them to pay all the time. It's why they look for such games through Gamepass or PS Now services.
It's not even only that. When there is an upgrade on the game immediately after releasing it to patch an unexpected bug, it wouldn't be a problem for you.
