This is a very Basic Icon. It doesn't give the wrong impression about the game, there is nothing sneaking or enigmatic about it. The P is the first letter of the game, so it clearly conveys it's purpose if you've read the name of the game.
I don't like this one as much, because it's a Face. A face doesn't give any focus or emphasis on the game or what type of game it is at all. You either know from experience what the icon means, or you don't.
This one is my second favorite, right behind the P.
