Let me get this clear for all of you, I AM NO EXPERTAT SIM CITY! In fact Sim City 4 was my first game I have in the awesome series. So don't ask me incredibly hard questions. I was so bad at this game when I first got it that I had to redo about ten whole cities. Now I get to what I'm supposed to be talking about. My city is currently at 201,094 people and I'm expanding my transportation systems. My World Trade Center has three buildings and a beatiful plaza. Because I downloaded these buildings, my CO$$$ demand droped greatly. So I destroyed the buildings and lowered the taxes to 0.5. Soon I got three new and large CO$$$ skyscrapers. Hope this advice helps. Thanks for reading.
