PS: SHODAN got PWNT by GLaDOS, just forget her.
I'm calling BS on that. I have trouble thinking of glados as sentient. Unable to become more than just a faulty AI, she just sits in her lab and keeps on hacking away at the tasks she was built to solve (using people as guinea pigs, I know. Seriously, doesn't anyone know about the three laws of robotics?). IMO she isn't even evil simply because you cant pass moral judgment on her because she doesn't understand the moral implications of her actions. Shodan understands that well, she just doesn't care. She is one of the most genuine, well rounded characters I've seen in a game and easily a better villain.
Over analyzing aside, glados was funny with a side of creepy. Shodan was malevolent and terrifying. As a villain at least, Shodan > Glados.
As for my pick, I particularly liked Deus Ex's Bob Page. A wonderful example of the Egocentric Industrialist with dreams of Absolute Power. As a classic despot, he's a true real-world villain and the game is all the better for it.
Speaking of egomaniacal capitalists, I'm surprised that no one has mentioned Andrew Ryan yet.
