While not as sexy as the 1979 quasi porno starring Malcolm McDowell and Peter O'Toole, the latest take on one of Rome's most notorious Emperors is ten times more satisfying.
Viva Caligula is a flash game where you play as Caligula. Since the whole empire was so corrupt, the goal is to sadistically slash your way through the Roman populace, including woman and children. Using 26 different weapons and tactics that you accumulate along the way, you gain points with each kill. If you're having a bad day at the office, this game is perfect for blowing off a bit of steam.
