The backlog thing is part of why I think we're in a golden age. I remember when I was a kid, it was common for my friends to own a game console (Gamecube, Gameboy, etc.) with less than 5 games for it. We're in an age of abundance now compared to those days.

I try to view my backlog as an asset, not a liability. Think of it as a garden of unexplored delights. It's just a matter of giving a new game 5-10 hours to prove itself to you as you master its mechanics, instead of skipping on to the next game if you aren't immediately hooked.
