Get ready to embark on two new railway adventures with Ticket to Ride Map Collection 5: United Kingdom & Pennsylvania! This expansion brings a double-sided game board, adding extra spice to your Ticket to Ride or Ticket to Ride: Europe games. On one side, you explore the British Isles, and on the other, the state of Pennsylvania in the USA, each with its own rule twists that will make you think differently. In Pennsylvania, the big novelty is the introduction of a stock mechanism. Whenever you complete a route, you can claim a share of one of the railway companies associated with that route. At the end of the game, whoever holds the majority of shares in a company earns bonus points, turning the race for routes into a battle for stock control! On the United Kingdom map, the innovation is the technology tree. Initially, your options are limited: only short routes and only in England. But by spending your wild cards, you can unlock technologies that allow you to build longer routes, cross water with ferries, and expand your network into Scotland, Wales, and Ireland. You can also buy bonus cards that give you extra points for certain actions. Oh, and an important note from the designer himself, Alan R. Moon: the Advanced Technology Cards on the UK map were included as a bonus and were not extensively playtested. He recommends using them only after a few games to avoid overcomplicating the first experience. Although officially an expansion for the mentioned base games, with a bit of creativity and spare trains, it's possible to adapt it for play with Ticket to Ride: Nordic Countries, albeit limited to three players.
