What do you use to tell stories for your Sims?

If I like a character, I don't make Sim stories about them- I put them in my own world, where I perfect their personalities, drop their plumbobs at the door, and become real story characters. They no longer can even be called Sims by the time I'm done with them. Chances are, you could read about them and not even think for a moment that their original selves ever spoke Simlish. Sims generates new character ideas for me like crazy.
