That's cool. I might look up one of his books, now.
I think it'd be interesting to see if there were a difference in mediums, though. Books and video games tend to attract different people (With exceptions, of course). Would the differences in audience affect video game sales the same way they affected Neil Gaiman's book? I could easily download and read books for free on my computer, or on an e-reader, but I prefer having the paper in front of me and getting away from the LED screens for a while. The most I've done is glance at a couple of books that I was considering buying.
Many computer games don't even come with anything physical anymore, so the same businesses that sell the games are discouraging that feeling of having something solid to go along with your purchase. Why should people want to buy a game at all when downloading it illegally is just as easy as buying and downloading it off of the company's website?
I've never illegally downloaded a game, and I don't plan to, but I have to wonder if Gaiman's thoughts could be applied to a medium so different as video games. I wish someone were trusting enough with the community at large to try it out.
I still think the sales lost from Piracy is marginal - Most of the people who download stuff illegally wouldn't buy it legitimately in the first place.
