Over at Salon.com there is a nice story of Rockband saving a gamer's marriage [1].

Here is a taste:

"I love it," I say, tired but exuberant. "My hands are killing me."
Still smiling, he reaches for me, and gently kisses my blistered palm.
"Let's take a break."

"No!" I cry. "I need more practice on 'Enter Sandman'!"

Ben cocks his eyebrow. "Well, I'm going to bed. I guess you can borrow my headphones if you want."

Blistered palms and sleeping alone? Yup that sounds about right for the video game addicted.
