Are the expansions worth getting? If so which are the best? Has anyone tried playing boys against girls with the girls using the sports deck and the guys using the girls night out deck? Is there room in the original box for all the cards of the expansions?
As the publisher of course we are biased, but all three expansions are great! We have not tried your "boys against the girls" idea in the format you propose, but I'm sure it would be a riot! The original box is made to hold two of the expansions completely (with their inner boxes intact). If you remove the inner boxes from the original and the expansions, then all the cards from all three expansions, plus the original cards as well, will fit inside the original box.
Enjoy the game and thanks for your interest--
