"A Spy Game About Subtle Behavior" and "A Puzzle Game About Observing People": Spy Party and Remote Shepherd

I'm reading this month's issue of GameInformer, and there's an interview with some guy named Chris Hecker. Some of you may have heard of him. Anyways, he's talking about this game he's working on, Spy Party. As I'm reading about this game where one player tries to blend in with a crowd of NPCs, and another with a sniper rifle tries to identify that player via behavioral cues, I think to myself: this sounds familiar.

Oh right, I just finished making a single player version of this game.
