I got mine about an hour ago. The first time I brought it up, some of the controls were a bit sticky. I tried to turn my Sim around, and he kept spinning. After I got him to stop, I couldn't do anything, so pressed CTRL-ALT-DEL to get out. My second attempt went much, much better, so if someone has trouble on their first try, I'd suggest shutting down and trying again. I noticed in the option menu that there's a button for laptops, so will try that next.
I made a brother and sister, to play with genetics. They look somewhat alike but not entirely. I love most of the hairstyles for women and the eyeshadow. I kept reaching for the opacity slider on the make-up though, and of course there isn't one. The clothing is great.
One thing I noticed is that you can only make young adults in the demo, but I haven't tried a husband and wife yet, to see if they have children.
I have two problems -- the first is that when I look at people on TV, I want to make their faces. The second is that now I want to play the game!
