SimCity 5 has been announced and confirmed by EA and Maxis. The new game is set to launch in 2013 and will be a single and multiplayer game.
The game will run on what is called the GlassBox engine and will bring extreme detail to the game not previously seen. Although the screenshot below is taken from the demo video, there is a footnote towards the end saying “Images not representative of gameplay” so keep that in mind while the renderings blow your mind.
