Fica uma entrevista com um dos produtores do jogo -> http://pc.ign.com/articles/614/614551p1.html
excerto:
IGNPC: Sweet Civilization. You realize I have to quit my job once this game comes out, right?
Barry Caudill: Yes we do, that's why it's good we work here at Firaxis...or we'd all be on the dole J Oh...was that rhetorical?
IGNPC: Anyway, let's start with the big picture. Will the basic arc or premise of the game change much from previous versions? Are you extending further into the future, for instance?
Barry Caudill: At its most basic level, this is the same scope of Civilization people have come to know and love. That means we still cover the usual time period of 4000 BC to 2050 AD, but it's how we make the journey that will set this game apart.
