Play God

• Sculpt mountains, gouge valleys, and seed forests to lay the groundwork for your creation.
• Drop a disaster anywhere in your city--set buildings ablaze, pelt your metropolis with meteors, unleash a twister, or wreak havoc with a volcano.
• Populate your terrain with animals that graze and roam … and sometimes stampede into your city!

Play Mayor

• Create, build and run the most realistic city you can imagine.
• Connect your metropolis with other cities you've created to form a massive region of SimCities, each sharing and competing for resources.
• Deploy police cruisers and fire trucks to the scene--you’re up close and part of the action as they deal with fires, striking mobs, crime, and more.

Play With Your Sims

• Place your Sims in your city--they'll give you valuable feedback.
• Follow your Sims to work and home.
• Experience life in the big city, from mellow traffic to commuter hell, noontime crowds to nighttime calm.
