Fable II Income Mechanics: Does Money Accumulate While Offline?
No, you do not gain income in Fable II when your Xbox is off.
Income is generated by your owned businesses (stalls, shops, real estate).
It only accumulates while the game is actively running.
There is no "passive/offline income" system.
Even leaving the Xbox on while idle only generates income while you're in the game world. To maximize profits, play actively and manage your properties.
