This is a great map for 2 or 3 players. There are some great destination cards that connect countries instead of cities. You get a bonus depending on how far away the countries are. My wife and I really enjoy playing this when we don't have a gaming group to play with.
If you like to play Ticket to Ride with only 2-3 players you must get this expansion. It is by far the best version I have played. It contains a new map and destination cards. You use your existing trains and train cards. It is designed to be played with only 2-3 players and boy is it competative. My husband and I play this game frequently. I especially like the addition of country destinations.
