Ever wanted to be evil? Really evil? Well, then you're mostly out of luck. Videogames are awash with brooding anti-heroes who are gruff and mean but ultimately good, but genuine villains in the lead role are pretty rare. For that matter, the few games with villainous leads tend to defuse them by pitting them exclusively against people who are even worse than they are (Manhunt, GoldenEye: Rogue Agent), or by playing up the whole "evil" angle for laughs (Overlord, Disgaea).
Games Radar put together a list to recognize the few, proud games that don't flinch away from delivering pure, unbridled villainy.
