The Sims 2: Open for Business

Help your Sims start their own business. From toy shops to restaurants, the world is your oyster – buy a plot of land and then fashion an empire to make Alan Sugar belch.
The lowdown:
The idea of a Sims business tycoon game may seem odd, but this is a surprisingly fun and accessible expansion. Although you can stay at home and create items to sell, most businesses are run from a new shopping centre area, which you can also visit separately. To run a shop you buy objects as normal, and then display and price them individually, or in bulk for your store. Running a restaurant or other service is more a case of creating the right mood with furniture and staff. You can hire and fire employees as you want, but its worth being as hands-on as you can because you gain a wide range of new skills from the work you do.
