Hi, Chronic,
I just looked at the Clone Challenge, and it does look like an interesting way to explore the game.
While I'm glad you're trying Strangers in a Sim Land, you'll need 3 Sims to start, although I suppose you could give your clones different clothes and keep track of them that way. Also it goes for 3 generations.
I've been working on a challenge that involves the Stylist and Architectural Designer professions. It's in the Proposed Challenges thread, fairly recent.
