Seamus Blackley, who spearheaded the development of the original Xbox and co-designed legendary PC games including System Shock, Flight Unlimited, and Jurassic Park Trespasser, says that the sale of Activision Blizzard to Microsoft will “torment” outgoing CEO Bobby Kotick. Explaining how he initially helped pitch Guitar Hero to Kotick, Blackley also describes how the Activision boss reportedly turned the idea down before purchasing the series years later, adding it to Activision’s substantial gaming catalog, which also includes Call of Duty Modern Warfare 3 and Diablo 4.
