It doesn't necessarily matter, but it is an interesting topic. In science, whenever there is a statistical anomoly, or something is skewed, it can be valuable to wonder why.

The idea that arcades were originally in primarily caucasian neighborhoods sounds possible as a contributor (if they were, I don't know). I would be curious to compare the demographics of kinetic pinball players with the video pinball group. One would assume the video pinball demo is similar to the XBox demo. And probably more diverse.

And Gambit, that sounds like a long story that would make for a good read!
