Good answers. Basically for me:
Time is the big factor. Especially now that I have a full time job, a wife, and a child...plus I am involved in some community things on weekends, and being a home owner I am working on fixing house projects.
With having a full time job, spending quality time with my wife, taking care of kid, house projects, getting at least 5 hours of sleep a day...yeah game time is little. Basically my main time for personal game time (Single player/adult multiplayer type games) I spend in the evening when everyone has gone to bed and my responsibilities are done. So by the time that happens there is little time for games...then its sifting through my backlog to figure out what I Feel like playing lol.
The other big reason is cheap sales. I honestly only buy maybe one or two games on release day a year. Those are the ones that I know I am really hyped for. All other games I buy are cheap sales of mostly $5, $10, $15, and $20. I rarely ever buy a game over $20 at all unless its a release day game I really want. Average price I pay is $10 on a game. I buy games that are less than $20 that really interest me and I know I will play them at some point. Buying any video game at $10 is hard to pass up when Im interested. So therefore lack of time and sales pile onto the backlog.
I would guess I have roughly 20 games I have not even played...a handful of which I bought 2 to 3 years ago. And another 10 games I have only played little.
