IGN had an interview with Cevat Yerli from Crytek, one of the shocking things they learned is that the piracy rate of PC games is around 1:15 or even 1:20. This means for each sale there are about 15 to 20 pirated copies.
The other critique outside Crytek was the fact that the PC industry is really, at the moment, I would say the most intensely pirated market ever. It's crazy how the ratio between sales to piracy is probably 1 to 15 to 1 to 20 right now. For one sale there are 15 to 20 pirates and pirate versions, and that's a big shame for the PC industry. I hope with Warhead I hope we improve the situation, but at the same time it may have an impact on [our] PC exclusivity in the future.
