Surprisingly popular transport management game Cities In Motion
has been regularly updated with DLC, and its latest lump of transport extras contains the ingredients necessary to keep London's commuters in motion, with bright red buses, the Gherkin, the Eye, and Buckingham Palace, as well as new scenarios and so forth to suit London's vehicular travel context.
The trailer (below) fails to show us London's bowels being moved by the Underground, but it's there, apparently. Also: trams. Not sure that's entirely accurate, but perhaps that's the point. The new DLC arrives on November 20th. I've also posted a documentary about Britain below for those of you interested in our tiny corner of the world.
