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.
