Some really fantastic suggestions and no doubt I'll come back to this thread next year too. Chloe, charades is a great idea, we tried it when she was younger and she just didn't grasp it, but she'll love it now (and has a fantastic memory for films and movies too).

*Update* We settled on the electronic "Deal or No Deal" (which conveniently happened to be heavily discounted at Big W) and we also got a Trivial Pursuit (some junior edition).
