I've yet to try Switzerland in my map pack but I enjoyed India. One note on your video though - at around 05:15 the Dice Tower intro with the dice mascot included plays in the background over Dan's voice! :P
Switzerland is fun, but you have to keep going for new tickets VERY early on. I find i play the same strategy on it every time regardless though. I avoid the bottom left and right corners as much as possible, and try and grab the 4 length tunnel to Austria early on, and then the black run next to it. I don't like wasting goes on those singles. I then go straight west to the top border of France Germany (lots of choke points to take there early too. If i'm lucky i can slot through the middle down to Italy. By now i should have at least 3 of the country-to-country cards because i hoarded them early (i don't take many actual route cards).
India is the best ticket to ride I've played. It's so cutthroat compared to US and especially Europe map it's unreal. Especially three player version where the double tracks are not open.
I still don't get the Mandala Bonus, is there any possible route that can loop up to 5+ times? For example, from Bareilly to Ahmadabad can have 3 possible looping routes because they both have 3 routes that can reach in both cities.
