During a regular season or playoff home game, pause and save the game. When game is saved, quit and go to the main menu. Reload your franchise file, which will take you to were you left off during that game. Everytime you do this it is like the computer charged the fans to re-enter the stadium because all income from tickets,concessions,etc. have now been doubled. I made $20 million during one regular season game in my second season by doing this four times(once at the end of each quarter). Do this only when you are the home team or else your just making alot of money for the other team.
