oh, it's probably truly well known, but if you have Sim City .. 4? you can make your own neighbourhood for Sims 2, and if you play Sim City you can place any of your sims from Sims 2 into your cities. Be careful placing trees in Sim City though because when you open it in Sims 2, those trees will be multiplied like a disease, so only place those very sparingly. There is a tutorial out there about how to make a neighbourhood from Sim City for Sims 2. It used to be on the old BBS exchange. Surely someone has kept or recreated it somewhere.
