Meh. If someone pirates a game, it is my belief that in the majority of cases, they would have never of bought the game in the first place, thus no sales were lost. On the contrary, for games which offer no free demo, a cracked game can lead to a sale when pirate cracks the game, finds he or she likes it, and then purchases it. In my opinion, enhanced customer support is the best anti-piracy tool available to game software developers. Things like access to official forums, patch access (or early, beta patch access), and official multi-player support will get any "pirate" who truly enjoys the game to eventually cough up the dough for the game. Generally this philosophy works best with developers and publishers that care about more than just the bottom line, and provide their customers with the incentive to want to support them by putting out solid games and listening to gamer feedback.
