haha..the Sims are so addicting! i have Sims Pets, Livin Large, Hot Date, Vacation, Party, and Superstar. its pretty awesome tho, playing with all those expansion packs.

Some Cheats (in case you dont already know):

Hold down Ctrl, Shift, Alt, and C at the same time for the box to enter your cheat.

Using the box type in:

~for extra money type: rosebud!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;!;! ;!;!;!;!;!;!; (however many of those !;!; as you want- the more you type the more money you get)
------------------------------------------------------------------------------------
~to get a good mood for your sim type:
move_objects on

then when you resume play, go into buy mode, click on your sim and delete it. then press the play button again. where the picture of your sim is, there will be a red + . Click on the face and your sim will have a good mood. (Note: save before you delete your sim, or else it will lose all its relationship, job skill points it earned from your last save.)
