When Steve Jobs unveiled the first iPhone in 2007, he described it as a revolutionary and magical product. Fortunately, the founders of the Finnish company Grey Area, the maker of Shadow Cities, were listening and found their platform for an engaging game idea: a location-based MMORPG in which you, and not an avatar, battle against other mages for domination of neighborhoods in your city. First launched in Finland on November 10 of last year, in one day it became the top grossing app in the Finnish App Store, to the surprise of Grey Area’s founders. Released in North America last month and now in 13 more countries in Europe, Shadow Cities is bringing an engaging, new spin on the typical iPhone game with alternative reality gaming…and it’s free to download from iTunes.
