The defining city simulation is back. Create the city you desire and make the choices that shape your city and power the citizens within it. Every decision, big or small, has real consequences. Invest in heavy industry and your economy will soar - but at the expense of your Sims' health as pollution spreads. Implement green technology and improve your Sims' lives while risking higher taxes and unemployment. Team up with your friends to solve global challenges: launch a space shuttle, reduce carbon emissions, or build magnificent wonders. Compete on global and regional leaderboards to be the richest, the dirtiest, the happiest or the best place to visit.
