I've felt this way at times but I don't know if it's me or technology that's changing the experience. The article mentions how games have become abundant with the Humble Bundle, Steam, etc., and that's a huge difference for me from when I was younger.
It used to be that games were more scarce, so you always gave them enough effort to get the most out of them. Now you can get them for a few bucks each, en masse, straight to your computer. There's so many of them and they all are asking for a investment of your time and personal interest that you can't possibly provide for every one. Most games require some initial effort to enjoy.
I had the same experience with music. During my downloading phase I would be able to get all this music and not listen to it. I couldn't invest myself in the music the way I did when one album was the only new music I'd have for a month at least. It started to seem like music just wasn't as good anymore.
