Ticket to Ride's "Legendary Asia" map – first introduced December 2011 in cardboard form – is available now in the game's virtual environment on iPad and Steam (PC and Mac), as well as the browser-based version.
The expansion is available as an in-game purchase for $3.99/€2.99. Ticket to Ride is also currently on sale through Steam at half-off for $4.99. So, come on ride the train and ride it. Sorry, you knew we'd have to use it eventually.
