Both have characters who are trying to escape from their despair by using their intelligence and sheer will to power through. They both fall in the dystopian category with Edward Elric's country being a military state, and the country itself being a WW2 reference with them as Germany. Over time in the story the situation seems to get even worse too. They both also have nice sound effects.
