En fjärde upplaga av Sid Meiers strategiklassiker Civilization kan vara under utveckling. Detta kan uttolkas när man läser en intervju med Firaxis-bossen Jeff Briggs hos GameDaily.
"Firaxis currently has three products in development, with a fourth that will "probably" be starting up soon. Pirates! and Civilization 4 are the only products that Briggs would identify, but he did shed some light on Firaxis' development cycle."
