I guess it really depends on what you define as an extended break. I've gone maybe a week or so without playing when I'm really busy, but usually I'll play at least every other day. It's just one of my favorite leisure activities.
The only time I took an extended break is when I was really busy and stressed with work. When I'm going through a period like that, I usually find something like reading or just zoning out in front of the television more relaxing.
I agree with you about Kinect, 360vixen. It requires a totally different level of involvement and energy. I'm really sporadic with games like that. As long as I'm playing a variety of games, I'm less likely to take a total break for more than a few days at a time.
I don't think my husband has taken a video gaming hiatus since he was about 12, lol. As for me, I guess I'm more like France9 because I can get on a kick where I play it daily for weeks at a time, then decide I'm tired of it and stop playing altogether for several weeks. I'd say the longest I went without playing was a few months.
