"In a break from standard industry practice, Bethesda decided to publish their strategy guide in-house, rather than contracting it out to a third party publisher like BradyGames or Prima Games. The decision resulted from a belief among Bethesda staff that they believed in and understood Morrowind more than any external agency, and deserved more royalties than were commonly rewarded. Bethesda hired Peter Olafson, a noted game journalist and friend of the company, and they began work on the guide in January 2002, four months prior to release. The resulting product, Morrowind Prophecies Strategy Guide, sold over 200,000 copies as of September 24, 2003. Although the royalties from most third-party game publishers approach 25% to 30% only infrequently, Bethesda managed a 70% profit margin on their own. In spite of this success, Bethesda decided to allow Prima Games to publish the "official" game guide for the release of The Elder Scrolls IV: Oblivion."
