I'm not surprised. On the flipside, my nieces and nephews love playing my pins and the Wii / consoles hardly attract any attention at my place. I certainly have no idea what is "out there" and what kids play in terms of coin op.
I'm "old school" and bloody proud of it. Sometimes I watch the kids play pinball and they get more excersize flipping then they do sitting on their ass playing consoles and vids. What I REALLY like is the fact that they DO show an appreciation for Pinball, sometimes you have to expose them to as many pins as possible to attain their interest. "Oh that's how you do it.."
My 6 year old can name over 100 pins and tell you what toys are on what pinball. Brings tears to my eyes.
