Have you visited Borgamo yet today? No? What’s wrong with you? It’s the best site for board games around. You can find information, pictures and places to buy games all wrapped up in an ultra-slick layout.
I must especially recommend the Ticket to Ride page. It’s got a lot of good info and a great quick explanation of the game, which is perfect for a noob like you.
I’ve also made a couple of TTR maps, one of which is for Ticket to Ride: India. It’s not perfect yet, but I’m fairly proud of it. Here’s a thumbnail.
Here is a ZIP file with the full-sized map and route cards: Ticket to Ride India.
If anyone else has made custom Ticket to Ride maps, I’d love to hear about them. I’m having a hard time figuring out the correct size to print mine out, so I would welcome any help.
