Do tell me about Totally Renamed Spy Game. I've seen it at our local specialty game emporium, but nothing on the box caught my interest necessarily. Briefly, how's it play & what makes it so worth playing?

(We have a Game Night event monthly, myself and some friends, and our Game Bag has about 30 - 35 games in it of various sorts, so ... feel free to reference games & respond as if you are talking to someone who is a game geek, cuz, I am.)
