An iPad is a great way to play bulkier games like
Ticket to Ride
I love my iPad but so far I found the pass and play method really unsatisfying, to the point that playing is no fun at all. While one player is playing the others have nothing to do, nothing to look at (the board, their hand, whatever), so it's basically as if you stop playing the game after each of your turns and you're forced out of the game, until it's your turn again and you find out what has been going on.
It makes the game something you're detached from.
the ONLY game that works in pass and play for me, of the many I've tried, it's Neuroshima Hex. As everyone said already, it's actually better than the tabletop version and I highly recommed it.
