The money glitch involves abusing Fable II's "make money whilst you're not playing" feature. You have to be making some amount of money from real estate (the amount doesn't really matter). Once you have some real estate that you are renting, or a store that you are making money from, save and exit the game. Then, disconnect your Xbox from the internet, and set the date on your system forward for however many years you want. When you come back to your game, it will think that that time has actually passed, and give you the money you would have gotten had you actually waited that long. You can set your clocks back and reconnect your internet afterwards and it won't affect the amount of money you "earned".
