One thing that we have learned is that piracy is not a pricing issue. It’s a service issue. The easiest way to stop piracy is not by putting antipiracy technology to work. It’s by giving those people a service that’s better than what they’re receiving from the pirates. For example, Russia. You say, oh, we’re going to enter Russia, people say, you’re doomed, they’ll pirate everything in Russia. Russia now outside of Germany is our largest continental European market.
That's from How Valve experiments with the economics of video games. Read how the today's model of Internet-purchase and -delivery allows much experimentation with pricing.
