The Two Towers strives for an accurate portrayal of life in Middle-Earth. Gold is heavy, armour is bulky, and a person only has 2 hands with which to carry things. If both your hands are full, you cannot pick something else up. If you are laden with gold, you should not expect to swim without drowning. These limitations provide a realistic backdrop to further your immersion into Arda and are meant to aid in your Role-Playing.
