Dark Souls is a game about heroes. Well. . .not heroes so much as heroism. It's a game about facing seemingly insurmountable odds - not even winning or losing to them, just facing them. It's a game about death. It's beautiful, tragic, triumphant, and sorrowful all at once.
But most important of all, it's a game where I can make my character look like a Nazgul, and oddly enough that encapsulates the above better than anything else I could say. Let me explain.
