I love spies and the games they play. A couple months ago, I came across a game of Jericho, billed as a spy game with skulking, hats, and nerf guns. All of these things are awesome. I had high expectations, which were handily exceeded in an afternoon of stealth, strategy, ambush, flight, deception, and bad-ass shootouts. If you secretly want to be a spy or secret agent, this is the game for you.
