GamesRadar has published a news article about Jake Solomon, one of the pillars of Firaxis. Over his carreer he has worked on Civilzation 3, Civilization Revolution, the XCOM titles and the recently published Midnight Suns. Despite having been at Firaxis for ages, he describes himself not as a Civ guy. He worked closely with Sid Meier and Soren Johnson on the design for Civilization Revolution though. He is most proud of Midnight Suns, for which he had been the creative director.
