To unlock all the scenarios, play the first game and
build the following on Pacific Avenue: a theater, bar, restaurant,
bakery, apartment complex, and clothes store. Build each of these
buildings as tall as you can with a medium quality. It does not
matter how much surface area you make them. You must do this before
the second time period. Then, save and quit the game. When you
restart the game, you should have all the scenarios unlocked and
the budget will read 100,000,000, but will never decrease (unlimited
budget).
