I tend to find one game that I enjoy and stick with that one until I find it boring. For example, I played the COD series on PS4 for ages, and worked my way through the various titles as they were released. Once they stopped being fun I moved on to Fortnite very briefly until I discovered Apex Legends. I'm still playing Apex as it has been consistently fun and challenging.
I find single player games get tedious very quickly. So stick with multiplayer for the competitive element. And you really can't compare against competing against actual people rather than AI. Maybe take a look at Apex if you enjoy multiplayer.
