Here's a better way to explain why the way I think is better.
If we go with the way that the game is being proposed at the moment, then it is just simply stating the obvious.
If we go with the way that I am proposing, tactics and skill can appear. People might all decide to go for the most obscure and lose points, while someone could go against it, a double bluff, and get loads of points for an obvious answer. It rewards proper knowledge, but also has gamesmanship, creating a better game for us to play.
