Do they have mods for the sims?

[sammizu0]

I downloaded everything else for the sims; skins, houses, walls, floors, blah blah blah...

Do they have any nice mods that change how the game works? Im not looking for anything specific by the way. I know about modthesims but it only has stuff for sims 2 and sims 3.

[mkp]

I am sure this is a real fan of sims from the way she is been downloading just about everything of the game that she can lay her hands on!! I really wonder if there are many mods that changes how the game works!? Anyway, nothing to lose by just asking around and if there is someone will surely given the information she needs - can't blame her - it is a game that you can really get hooked to!!
