My job is largely based around describing games. A good description might be useful to you, or funny, or poignant. It might be revealing about the true nature of the game, or say something about what it means. Currently, I am struggling with this when faced with the developer's own description of Banker's Dozen. Here it is: "Based on the forgotten occult writings of a Nobel prize winning economist, Banker’s Dozen is a game about time traveling financiers." Which means that it uses relativity and finance to teach you about... relativity and finance. I'm not sure it really does either that, but sometimes an idea is all you need.
There's an explanatory video below.
