I got the demo yesterday and I was thrilled! I spent a lot of time messing around with it. The sculpting aspect takes some getting used to, but it is nice.
The clothing feels really limited, especially since I have both a ton of store items and use create a style constantly in the Sims 3. I think I will miss create a style less once there are more preset choices in it. It is very nice to be able to easily edit a different outfit and put different hairstyles on a sim with a click, compared to having to click through one or two screens and wait for it reload presets that, at least in my CAS on the Sims 3, takes forever. (My user preset file is over 4 MB, so that gives you an idea of how much I use CASt, and how badly it lags, even with a solid state hard drive.)
I'm also glad I'm not the only one that couldn't figure out how to get screen captures within the program. I have Fraps on my computer, so I just loaded that up for the ones I took, but I noticed there is a "Screenshots" folder in the demo, so that means there must be a way, right?
You can now choose a saved household and return it to Create-A-Sim and add more to it. I'll edit this when I've completed the husband for my current sim and saved the household again to see what happens.
I noticed that as well, and I love that feature! No more having to re-create a household to fix something minor, and having unnecessary copies sticking around if you forget to delete the old version!
What I couldn't figure out is if there's a way to save sims individually rather than in a household, so you can add them? Or do you just have to merge households until you get the sims you need into it?
