Farcry 3 - Vaas Montenegro
Vaas is great. Seriously. He’s a sociopath and a murderer, but he’s psychological as dicks. Farcry 3 was one of the best games of 2012, and Vaas is definitely a villain made to match. Equal parts intelligent and psychotic, you knew this guy’s faith only laid in one place: himself. FC3 was fully of colorful characters, villain and hero* alike, but Vaas really shines out.
*(Aside from Jason and his friends, they were all sucky and boring and seeing them suffer was more rewarding than actually saving them.)
