E3, the Electronic Entertainment Expo, invaded the Los Angeles Convention Center from June 12-16, and left craziness and delight in its wake. I’ve never been a great fan of the shoot’em up games. Instead, I searched the humongous displays in the Los Angeles Convention Center for build’em ups. I found two: a relative newcomer, Farming Simulator, and the newest iteration of a classic, Sid Meier’s Civilization.
