The game is a slightly scaled-back version of the big-boy Sims games. In this adventure, you live in a small town surrounded by a handful of neighbors, a few employment opportunities, and a few shopping areas. If a full-blown PC version of The Sims equates to Sim City 3000 or Sim City 4, the iPhone version of The Sims 3 would dovetail with SimTown. Perhaps Sim Small Town, even.
