Tips

1. Start by placing residential zones to grow your population
2. Add commercial and industrial zones to generate income
3. Balance your budget - don't build too much at once
4. Place parks near residential areas to keep citizens happy
5. Industrial zones generate good income but reduce happiness
6. Roads are cheap - use them to organize your city layout
