I didn't get around to doing this previously with Sims 2, so I decided I had better get this posted before I got much further in Sims 3. These are the custom content items I am currently using in my game:
( DEFAULT Replacement Genetics )
( Non-Default Genetics )
( MODS and Extras )
( SIMS 3 Sites I Frequent for Content ) *Just as a note: I'm having trouble getting my links to stay, so for now I'm not linking the sites directly... I'll fix this when I have more patience for it.
