When they run out of states (and if they can actually deliver 50 games, that would be a grand achievement!), they could use US territories. If they are charmed enough to use those all up, they could always use the names of all the countries we have mucked (be it for the purpose of humanitarian aid or hunting for weapons of mass destruction) with over the years (Somalia, Panama, Haiti, Iraq, Afghanistan, etc)
Since it will take time to deliver so many games, I imagine the list of invaded countries will have increased by then, so there should never be a lack of nomenclature.

Personally, I think the Bush family is a weapon of mass destruction.
