I've replayed it recently. From saying I would just have one decorator, I actually have rivals - a male and female decorator. There are only so many gigs to go around so there is competition. Actually, someone who wants to could do that with a bunch of contestants. It'll definitely stay among the playable careers that I replay. Mainly, I go into more detail with the decorators and then I keep the builds. It is a way of customizing the houses more. I said this before but if you want to play with the career or really want the design styles then it's a good pack. I will say that the new build/buy stuff does upgrade the look of houses.
One criticism is the uncomfortable moodlets for the new sectionals. They should be great to use. I've also noticed a few routing issues when going into live mode as the clients later because I rotate. When I've rotated, I have noticed some bugginess in those houses that will hopefully be fixed, mainly routing and sitting.
