I don't really want to post in this but here you go.
The people who pirate games.. will always pirate games, no matter what. Protections, no protections, reasons, no reasons, whatever.
When you put out a quality game, people buy it. The people who don't pirate, don't pirate for whatever reason. Some for morality, some for tech, some annoyances. If a game is worth the the money, people will buy it. People will also pirate it. See above.
