Speaking of excellent tabletop RPG design (we were, weren't we?), I just noticed The Valedictorian's Death.
This is by Paul Czege, the guy who did My Life With Master, and it is both stomach-churningly creepy and awe-inspiringly brilliant. It is a game about looking through the real-life yearbooks of people you don't know, roleplaying the graduating class, and working out who is the culprit in the fictionalised murder of the year's valedictorian.
It's co-operative storytelling, where player stats are entirely about influencing narrative rather than resolving conflict. These rules are actually solid and gamelike, rather than vague and wishy-washy, and at the end a winner is determined in a way that promotes both competition and storytelling. Also, it is 100% free to the public.
You have to check it out right now. Right now, dammit. I am five kinds of envious.
