Available today, SimCity Mayors can get the Amusement Park DLC content, which enables you to customize and build your own theme parks. The DLC includes nine rides, three entry gates and five concessions stands, but there is a challenge to building it right to make your Sims happy (think small scale RollerCoaster Tycoon).
SimCity also saw a recent update. Released last week, Update 4.0 offers the free new map, Edgewater Bay, with a theme park-centric city in mind. Also included in the new content are five new missions to play through and with more to master in the Tourism city specialization.
The Amusement Park content is available for $9.99/£7.99. For more information, head to http://store.origin.com/store/ea/html/pbPage.SimcityDLCNA.
