The city-building simulation MMOG, CitiesXl, developed by the folks at Monte Cristo has launched in North America today! CitiesXL features a robust feature set of city building tools for aspiring mayors, but unlike traditional city building sims, CitiesXL also features a fully online component called the Planet Offer.
Players who subscribe to the Planet Offer ($9.25/month) will be able to build up to five cities, receive regular updates to the game, and trade with others.
For more information on CitiesXL visit the official website here.
You can also watch a in-depth walktrhough video of the game's basic feature set. Interested in the Planet Offer? There's a video for that, too!
