Fatigue

In the last few months I've noticed an interesting change happening in myself. My enthusiasm for playing games seems to be decreasing over time. I'm not sure if this is a function of getting older, having more responsibility in life or a sign that perhaps I am outgrowing this hobby. For years I looked forward to the time at night when all my work for the day was done and I could relax with a controller in my hand. Now it feels more like a chore than something to unwind before going to bed. My enthusiasm seems to be waning and instead of turning on a console at night I opt to watch a movie or TV or even read a book. I'm not really sure what to make of this change. I wish I could pinpoint why it was happening specifically or think of ways to make this hobby new and fresh for myself again. I want to point my finger at the industry for creating a state in which all games are so similar that nothing seems fresh but that doesn't seem quite fair. I can't possibly be without blame in losing my interest for the hobby.

Have any of you folks out there gone through this? What did you do to reinvigorate gaming for yourself?
