Yeah, and its more or less the same thing as Hollywood claiming piracy or copying destroys their industry. I think in general game developers miss the point about piracy: - its free advertising. Just like radio is for music. - maybe pirates will not buy your game this time but they may buy the next. - simply your game is not attractive enough and most people dont want to spend any money on it. It's not because your game is cheap that it's worth buying.

If you complain so much about piracy, go in free to play mode and make your fans buy extensions or addons. This is known to work well if your game is designed around it.
