What can I do to bring back my love for the game?

I haven't lost interest since I got the Sims 3 and I've played the same way for years. But I like to build. If I'm bored, I start in a new world, rebuild the entire town and then do my families, sometimes I might use a few of the townie ones but not usually. And I do bios for all of them, all intertwined. Some good Sims, some devious sims, some bad. Have a little story going. That's what I do.
