I have a LOTR and Tron paired up and I think its awesome. You have the deep rules on one side and you have the quick/kick your ass futuristic theme of Tron on the other.
If money is no object I would have a MM with LOTR.
If we throw into the equation "games that are not available as of yet" I would go with BHZA and Magic Girl FTW (for the win)!!!!!!!!! WOZ and XMEN dont stand a chance against that!
