“Piracy is hard,” Cloud said, in a response to an audience member’s question about the issue. “It’s really, from my opinion, destroying the PC market.” He said concerns over piracy were the biggest factor in PC gaming’s shrinking presence in many retail stores. However, he maintained that he felt the PC gaming market as a whole was not in any danger. “I don’t think the PC market is shrinking at all,” he said. “I think there’re tons of people playing games on the PC. I think World of Warcraft is a good example.”
Some good points are made here. There’s no doubt that MMO’s by themselves will hurt other PC genres though, in addition to piracy.
