I just picked up a game pack of Pirates of the Caribbean cards today, and when I sat down to enter the ships, crew, etc. into my existing spreadsheet, I discovered that the index was completely different from the first ones I had.
Is this the case with every iteration? Or just with the Disney license?
The index cards that came with my original sets listed the ships in the order of the numbers on the deck cards.
The Pirates of the Caribbean ships have different numbers, and some of the ships in the earlier series don't correspond to the numbers on the PotC index.
So I'm guessing that each series has its own index and you have to know which series is which to be able to tell what you have.
