With enough money, anything is possible. All your dreams will be achieved, all your problems can be solved, and everyone will treat you with the respect you deserve. All you need to do is save every penny, barter every deal, and pick up every copper piece you find on the ground.
Additional Rules: Keep track of the highest amount of gold you have ever had before, updating it whenever you break that record.
Experience: You gain experience if you have more gold than you did the last time you gained experience this way.
Complication: When money is involved, you can't take no for an answer. The next time someone offers you money in exchange for something, you must accept it.
