Quick money:
Enable cheat mode and enter the rosebud code. Display the cheat prompt again and type !;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!:!;! (up to sixty total commands may be entered).
Enable cheat mode and enter rosebud;: as a code. Then hold [Enter] so that "No such cheat" begins to flash. Keep the key held to gain up to 99 million simolians. Note you can replace : with any invalid character in the cheat.
Enable cheat mode and enter rosebud ; ; as a code.
Once you reach 9,999,999 simoleons, it will stay that way for the rest of your game.
Free Simoleons:
Buy a rocket launcher. Have your Sim launch the rocket, and watch where it lands. This only works if the rocket lands within your property, and may require a few attempts. When the rocket explodes and disappears, go to buy mode and move the pointer over the square where the rocket was located. Click on it and the screen will say similar to "Toy Rocket: Down/Exploded $2,300". Sell the rocket for 2,300 Simoloeons. Considering the rocket launcher is only 40 Simoloens, this is a very good deal.

Get abducted by aliens:
To get abducted by aliens, buy a telescope and gaze at the stars at about 2 or 3 in the morning. Be patient, your Sim will soon be abducted by a strange light. Note: Once your Sim is abducted, you will never get him/her back. Its good to save the game before you try this.
