Do you incorporate faith/religion in the Sims?

To answer the title of this topic - no, I don't. If it was implented in the game the means and gameplay to develop/support an imaginary religion, I think that would be a lot of fun to mess around with. Most likely, I would want to create a Watcher-based religion since I play the game and direct my Sims' lives. But I personally don't feel that real life stuff belongs in a Sims game. That because I seperate game and reality and like it so.
