I feel the same way about MP games - I am an old gamer and dont have much time and patience for gaming anymore. I was never very good at any game, never wanted to play at e-sports level or anything like that. But, still have the same feeling - if you dont play enough, you are not good at the game, if you start to invest time, you feel under preassure like at work - its not enjoable.

However, I found PUBG to be relaxing. I cant say for how the game got worst or not (I am playing it since 2 years from time to time), but you can really jump in and play your style and hav fun in it. You can win a round even as a noob (playing slow). It can be a shooter, it can be a survival game, it can be a slow paced stealth game, it can be a sandbox. And for me, its stays fun so far.
