@CWO:
Yes, the Pacific 1940 2nd Edition uses the thick, heavy duty cardboard like Europe 1940. Not that thin stuff like in Pacific 1940 1st edition.
And as I recall, the roundels in the 2nd edition of Pacific 1940 and Europe 1940 are both printed on thick, black-backed cardboard. In the 1st edition, I think one of the games had white-backed roundels.
You’re right Marc.
