It doesn't seem like copy protection that makes the game un-fun to play is really a good idea. It seems more likely to backfire as it might generate bad word of mouth for your game. "Damn, that game sucks. Glad I didn't buy it. Better warn my friends" IIRC when we made Gunship for the Commodore 64 it had something long these lines in that if the loader was tampered with the helicopter wouldn't get enough power to take off. Whether or not that was a win for anti-piracy I have no idea. I do know the game was completely pirated within 2 weeks of shipping though even though we had gotten some fancy copy protection. At least the copy protection added a fast loader so it was a plus for the user :p
