No shit, sherlock.
As for the MVP... I think most people played terribad, from what I've seen
I think Claw/Fyodor was good up until day 3, but after that he made himself obvious as Alexei/Kromos was fishing. Maybe he was smart to get the people who might see through it killed first, though. He's definitely the player that dominates the game and he's getting away with it, so I guess he's the most deserving.
Jailor was megafail to put such blind trust in anyone and outing other important people to a completely unconfirmed "investigator," huh? Potentially guilty until proven innocent.
