No, I haven't accidentally messed up The Witcher 2's title, but instead, to pose a question.
After playing Dishonored, Hitman: Absolution and Assassin's Creed III all within a short timeframe of each other, I thought about who was the best "assassin" out of Corvo, Agent 47 and Connor.
Despite being in a game titled Assassin's Creed, I decided that Connor was the worst, Agent 47 in the middle, and Corvo as probably the best, due to if you played through each as a 'perfect' playthrough, nigh on nobody would've known you were there in Dishonored.
But they are by no means the only assassins on the video gaming block, so I ask, who would be your "King of Assassins"?
Personally, including Hitman's whole series I would have to say Agent 47 is definitely up there, with many a mission, where you can enter, dispatch of your target in one way or another, and leave without anyone knowing you're there, which would rank pretty highly up there as a the embodiment of an assassin.
