The real advantage of an electronic version of Ticket To Ride is that the Xbox 360 can keep track of scoring, ticket destinations and cards for you. You can't lose the plastic pieces in the electronic version or have the dog chew up the train cars. And Ticket To Ride lets you play a great board game with partners available for play any time of day or night. Unfortunately, Ticket To Ride: Europe would be more accessible to new players and more fun for everyone, and is clearly intended to be a premium expansion.
So despite being a solid game, you can play in a PC web browser for a lot less than the 800 points ($10) the Xbox Live Arcade version demands, and you get to play Ticket To Ride: Europe right off the bat.
