Together Aga and I make The World’s Most Respected Sims 2 Fan Group. And as one of the founding members I would like to pimp the ultimate Sims 2 resource I’ve found online to date:

Parsimonious Sims is the ultimate collection of Sims 1 and 2 downloads. Most of the objects and skins are of the highest quality and comparable to the ones that come in expansion packs – the best thing is that everything you desire there is completely free!
