This map was designed to be 100% compatible with "Ticket to Ride: Märklin" rules, including merchandise tokens, passengers, long and short destination tickets. But it can be used with any other Ticket to Ride edition, just ignore the city dot colors. The board is available in two versions: The light version is recommended for 2-3 players. Few double routes make it difficult to reach some areas if you play it with 4-5 players (which can be nice if you like cut-throat games). During play-testing, the light version makes it difficult to complete some routes in the end-game. The advanced version is recommended for 4-5 players and contains more double routes. This version is better for those who don't like others to block them. To get the map files, contact the author by Geekmail: https://www.boardgamegeek.com/geekmail/compose?touser=helioa
