I loved this expansion pack. It was the most creative yet, and there were different options for it; you could either set up a business at home, or buy a downtown plot and start there. Personally i prefered the home business as then your sims can rest while their employees work, and it is just a lot easier. It is also nice feeling in control of a business, and feeling the rewards when your business gradually gains stars. There are new items such as tills and shelves which also add to the experience. Your sims can sell anything they want, and they are also able to craft their own toys and flower displays, so there is a personal feel to it.
If you like Sims 2 – buy it!
