(Re: screenname, I am not, nor have I ever been, an Iraqi city.)
As a small child, I had the Sims 1, and all my female Sims had the same head because I thought it was pretty. I didn't see a problem with this.
I currently have a story thread, which isn't exactly a planned out story but also definitely isn't a legacy because I cheat like a boss and don't have the heart to kill off my original Sims yet. Also because I don't follow any legacy rules. So I don't know what you'd call that.
