Sim City Classic PC Game Cheats

Instant building:
Hold [Ctrl] and attempt to build over objects.

Keeping citizens happy:
To keep the citizens happy with you as mayor, lower taxes to zero. Just before the end of the fiscal year (December 31), pause game play and raise taxes to the maximum. Then lower them again in January. Taxes are not collected until the end of the year, so they do not have to be raised to the maximum until that time.

More Money:
Before you start the game hold shift and type 'fund' watch out though every third time you do it an earthquake occures, this is why you should do it before you start.

Save money while deleting highways:
When you are deleting highways, just destroy one half of them. You will save five Simoleons for each square.
