Ticket to Ride is OK. I found Carcassonne to be complicated, but only played an iPad version.Carcassonne is simple to play but endlessly complex tactically. It's also very different.
Ticket To Ride combines all the best aspects of both board and card games.
Dobble is very good for all the family. It's quite cheap too - around £10. It's a bit like Snap, but there are lots of pictures on each card, and one of them always matches the card in the middle. You have to say the name of the matching picture. E.g. Moon. The first person to find the match with their own card wins both.
