When I played The Sims 2, the first thing I'd do is create a small public lot where everyone could get all their needs met and buy food and a cell phone (since starting characters didn't have one). There were some oddities, since Sims get dirty quickly, I'd replace sinks with showers, and would make sure coffee was available everywhere.

Eventually, sims could walk from their home, rather than investing in a garage and a car or taking a cab.
