What the others said.
Maybe you need to take a break from games and indulge in some other, or new, hobby.
I like audiobooks, electric skateboards, cycling, manga… And more.
You could also expand the kinds of games you play. I keep trying new genres and if one gets boring I try something else.
Don’t force yourself if you aren’t having fun. That’s a quick way to really ruin something you like.
I’ve gone through several episodes of feeling like there’s nothing I want to play… But, if I keep giving things a chance, and make sure not to burn myself out by trying to find something too hard, or forcing myself to play something because it “supposed” to be fun, even when right then it isnt, something eventually gets me hooked right back in.
Most recently that has been Deadlock. I can’t get enough of it and the feeling is the best.
You might just need to reduce choice anxiety.
Once my library got really big, I would find time to game, but then waste it on figuring how exactly I want to spend the time. End up on youtube or something and not actually get into a game at all.
The solution was to keep just a few games favorited, and forget the rest existed.
When I’m done with a game, it gets unfavorited. When I buy a new game it gets favorited.
If the list gets too short, I might do some spelunking in my library to favorite something from my backlog.
This way, each time I sit down to game, I have a very short list of stuff to start or continue that I might actually manage to pick from.
