Yeah, SnappleMan's spot on. After what I've seen, those who pirate games and software are usually young people who can't afford the real product yet. Testing/using does give a certain brand loyalty. I myself have discovered most, if not all of my favourite bands through downloading mp3. Now my shelves sport their whole discographies.
But on the other hand, I've read quite alot of BS pro-piracy stuff from people who never buy games, software or music legally at all. There are different types of pirates.
