Its funny that you would mention how the cracks broke the game for you. the same thing happened to me, I want to say the unlimited money code was "glittering prizes" typed over and over again for 10,000 dollars.
I soon lost interest in the game as it was now easy as pie to buy anything. On another note, why do they say "easy as pie" ? I tried making a pie once and it was friggin complicate as heck.
yeah, it was a mistake. It was also a lesson learned because later i would avoid using codes in games because the cracks have the ability to ruin almost anything that you use them in.
