Raiden. Something happened to me last night when I was driving home. I had a couple of miles to go. I looked up and saw a glowing orange object in the sky. It was moving irregularly. Suddenly, there was intense light all around. And when I came to, I was home. What do you think happened to me?
Not even touching the meta story, the gameplay is totally fucking solid and probably some of the better stealth gameplay of all time. High skill ceiling for harder difficulties, plus with the sons of liberty you get a shitload of awesome VR missions that strips away everything but the basic gameplay. That, plus the snake tales, gives you hours upon hours of good gameplay and levels, and the game has plenty of options and tools to minutely tweak difficulty and custom fit it. Plus, Pliskin is the best character in the whole series.
