I have suffered from this at times. Mostly from friends worrying about 'value propositions' or whatever. Now I just play for enjoyment. If I ain't digging it, I move onto another game for a while. I can always go back if I want, but it is ok if I don't want to go back.
I think this tends to happen when a game throws too many mechanics at me that I don't care enough to learn because the game isn't grabbing me.
I find keeping a couple games in rotation also helps. Keeps things fresher.
Currently playing Last of Us part 1, as I've never played Last of Us. Enjoying the more on-rails experience, compared to open world.
