Architecture of Aggression Part Two on Damage Gaming offers opinions from several developers about their favorite video game villains of all time. The article offers entries from Lee Perry, Kenn Hoekstra, Tom Hall, and others on the topic. My personal runner-up vote would go to Ensemble's Mark Terrano's and my bro Rogue's Robert Selitto's pick, the Doom Cyberdemon, but for the scariest and most intimidating of all time would be the Arch Vile from Doom II (which is also picked by LithTech's Paul Butterfield).
