Once you truly quit for good it is hard to get back in

Long story short, I was at a friend's house for some stuff yesterday and got a chance to get my hands on a PS4 once again. I sold mine last year. The game I tried was god of war the new one with the axe. I remember playing God of war 3 on my PS3 and I had a blast with it. But unfortunately for the new game, I just got bored after around 30 mins. It is basically kill monsters over and over again to progress the story. So repetitive, so boring. TBH, I would rather just watch my friend play for the story than push the buttons myself. Gaming is just hard to get back in after a person truly quit for good. I must have completely lost interest lol.
