We are big fans of Ticket to Ride, and having both the America and Europe versions and recently added the United Kingdom Map Collection set too.
In this variant, there is a 10 car long route from Southampton to New York, which even does not need any technology cards to build.
Our games merely reduced to a competition who can build that route first, because in every single game, regardless who does it first, that person wins the game, whatever tactic (longer routes, more Tickets, etc) other players try.
How to beat that Route? 40 points in this game variant for that route seems extremely much.
