Well, I just complete my first (and likely only) Sims 3 Challenge.
My Sim completed 22 unique sculptures, for a multiplier of 2.1.
I'll need a ruling for my earnings. My Sim's last sculpture was finishing - no joke - at 11:57 PM, but because of the animation, didn't sell it until several minutes after midnight. So, final score is one of the following:
With final sculpture:
24,847 x 2.1 = 52178.7
Without:
22,794 x 2.1 = 47864.4
I've never really been much of a power simmer, but when this is all over, I really want to know how people were able to sculpt 70+ sculptures in 2 weeks. I thought I had a good plan, but I only got 32 finished.
