I really don't like the look of the sims in TS3. I'm not sure quite what it is I don't like. (Probably the fact they look like they're made out of playdough).
Also, there's no way near enough clothing and hair options. The colour slider is a great idea, though. The fact that the rest of the 'hood keeps going while you're in one household is a good idea if you like playing legacies, but you really should be able to completely switch it off completely...
I'm quickly disliking this game, despite the fact I haven't even played it yet.
