PC gamers already got their Devil May Cry 4 demo earlier today, now it’s time for some demo love for the console gaming crowd. Available starting today on the PlayStation Store and Xbox Live Marketplace is a playable demo of Sid Meier’s Civilization Revolution, 2K and Firaxis Games’ civilization-building strategy game coming to PS3 and Xbox 360 on July 9th (it’s coming to the DS, too). The demo features both single-player and multiplayer modes playable as either Cleopatra of Egypt or Caesar of Rome, with a handy tutorial tossed in to show you the ropes.
