I’ve recently caught onto the moodlets thing, too. Some guys nearby were goofing around while I was trying to focus on something important, and I gave myself the “Surrounded by Idiots” moodlet. I don’t even think most of the moodlets I give myself are even in the game, lol.
Oh, and I started using The Sims 3 as a tool for taking pictures of objects to use in green-screening. Would you like to see a Motive Mobile out on a random (real) street? So be it.
