I loved this game, played it to death, I built a 100 floor tower with a chapel, subway and even its own recycling plant. Then I got bored and let the terrorists set up us the bomb, and heaps of innocents died a horrible death.
DON'T build condos, they suck, you have to pay the bond back when the tenants move out and that puts you in serious debt. Instead build heaps of offices and let the game go on by itself for hours, then you will have millions of dollars.
