List of Custom Content Sites
1. Mod the Sims - perhaps the de facto favorite site for Sims players, Mod the Sims is the place for unique objects, clothing, and Sims for both the Sims 2 and the Sims 3. There are also a large amount of mods that will modify the game to create the ultimate unique Sim, everything from making your Sims read faster to fixing some of the inheirant issues that plagued the game at first release. In order to download, simply signing up for the site allows complete access to all downloads, comments, and forums.
2. The Sims Resource - one of the larger Sims sites, this site holds downloads for all three Sims incarnations. While the site itself does included paid membership, there are many objects that can be downloaded for free. As with MTS, a simple sign up is required for downloading.
3. EA Store - not many players are happy with the EA store that furnishes a lot of Sims 3 content, however there are objects and recolors that are offered on the site for free for anyone player that has bought the game. In fact, points are given when a new user installs and signs up for the main Sims 3 site. Among some of the free items are the free Toyota Prius and the second world of Riverview.
4. Sims 3 Forums - within the various listings, there are some topics in which discuss finding those hard to find objects (hair, clothing), along with posting links of where to find them. As listed, many enjoy MTS or TSR, but there are sites that come up that either are strictly for Sims 3 or have updated their current sites for Sims 3.
