SimCity: Cities of Tomorrow looks a century ahead and gives players a choice about what kind of future to build. Three paths are available: clean, sustainable technology guided by idealistic urban planning principles; massive MegaTowers that stack vertical density as the answer to urban sprawl; or the full consumerist vision of a world shaped by a single enormous corporation's priorities. The expansion adds OmegaCo as a fourth faction alongside the existing three, introduces Academy buildings for futurist research, and lets players build and manage the transit, energy, and waste systems of a city that hasn't been built yet.
