Indie developers 2D Boy revealed figures last week that indicate that the piracy rate for their puzzle game World of Goo may be as high as 90%. This statistic is based on the number of sales versus the number of IP addresses that submitted high scores. The game was released without DRM, software specifically designed to hinder pirates. However, developer Ron Carmel notes that Reflexive Entertainment’s Ricochet featured in-house DRM and was pirated at a similar rate (92%).
