Hi
that would be cool to have different shops (actually iw would be fun to have a mall) and a cinema, and different restaurants.
Also it would be great, once you have bought a ticket to travel somewhere, to actually see the place, and not only to take the plane. One could have some shopping in, say, Paris or London, or Chile or China...
Another cool stuff would be to see a doctor coming when a tama is ill, and maybe to have your tama going to school (elementary, secondary, university etc...)
oh, and what about tama-radio?
