I haven't played it yet, only because I have the sinking feeling that I'll need to replace my whole computer to play it.
As long as the house-building aspects are improved, I really won't care. The little architect in me just loved that game to death... well, except for that time when I killed my Sim (who was named after my sister-in-law-to-be) when she had an unfortunate kitchen accident. I had run out of money, so I never put any tile in there, so when the stove caught fire, so did the grass and her along with it. I freaked out, then screenshotted it to show her.
