When I was younger I thought I was the best Goldeneye player in the world. I firmly believed that. Now we have the internet and every day we are beholden to how terrible we are at everything, even the things we're actually quite good at.
Point being: some people are really, really good at Dishonored.
And it makes for phenomenal viewing. Here is why I like games like Dishonored and the Metal Gear Solid games: they truly allow for pure performance. They allow you to play in supremely stylish ways. I think that's a stealth thing in general.
Regardless, even if you haven't played Dishonored -- but even if you have -- this is a super fun watch.
