Digital Chocolate's budding Empire franchise makes a detour into downtown Rock City, turning the one-time nightclub management sim into a tour of duty in the metal bar scene. Instead of just overseeing one club, players must now juggle three exploding rock venues, giving the game a serious infusion of depth or difficulty, depending on your ability to keep booking new talent to please ever-fickle tastes, buy new equipment, and keep the staff happy. It's a smart evolution for the Empire franchise -- this is not an easy re-skin like The Sopranos Bada Bing! Manager.
