SimCity Cities of Tomorrow is an entirely new way to play the ultimate city-building simulation. Players have the choice to create a utopian society underpinned by clean technology under the auspices of The Academy, or encourage giant corporation OmegaCo to strip-mine natural resources and pollute in the name of making massive profits. These new specializations are set against the backdrop of the all-new MegaTowers, massive structures that players build high into the sky and dwarf the rest of the city. With the right balance the MegaTowers become self-sustaining monoliths that cater to all of the needs of the Sims under one roof. When players have finished deciding whether they want their Sims to live together in harmony, or as members of an exploited workforce, they can rain chaos upon them by unleashing an all-new disaster exclusive to this expansion pack.

The SimCity base game is available on PC and Mac and was developed by Maxis. The base game and expansion pack are cross-platform compatible, so all players play together across the same servers. Owners of SimCity Cities of Tomorrow can play alongside those who do not own the expansion pack and provide them with futurization benefits when they play together in the same region. Launched last March, SimCity has had eight major game updates that have made upgrades to the core simulation and provided game content at no additional cost.
