Tom Vasel's Summary:
Large cards and a whopping thirty-five new tickets are a good enough reason to picking up this inexpensive expansion. It turns the original Ticket to Ride into a more tactical game, almost putting it on par with the strategy king of the series - Ticket to Ride: Marklin. So, in summary - large nicer cards, more variety in tickets, a great new bonus card, and interesting forms of playing.
