Yep. Fat faces and dead doll eyes.
They don't HAVE to be fatheaded. AwesomeMod can let you reduce the head fatness beyond what the game would limit you to. And the eyes...well, did people really like the TS2 eyes, either? I saw a lot of replacements there, and nothing has changed here.
Maybe. We'll see if this terrain editing or making thingie EA is supposed to be bringing out works. Then I'll think about thinking about Sims3. But as it's an EA production I suspect it'll be right up there with Body Shop and the Custom Content program they made for Sims 2.
