Paris has the most routes in and out, but Stockholm has the most valuable route to offer.

The epicenter of the board is Paris with 10 total routes. Meanwhile, Stockholm, which only has three routes in and out, has the most valuable route on the board at 21 total points. Paris would be a crucial city to lock down in order to block other players, but laying tracks to cities along the edge of the board will guarantee less traffic, and potentially more points per route.
