I have this game, and I like it. To answer some of these questions: The map with the most land that isn't a scenario is map 61. It is a great map because the river separates the land into two large halves, and there is a small island that is perfect for the airport. I have achieved megalopolis in Sim City, but it is very difficult. You have to pretty much cram people into your city by developing every square inch of the map. You have to strategically plan how much land will be used for power plants, transportation, police stations, fire department, etc, and be able to place as many zones as possible.
