1941 was printed as a mass market game, it was $20 at US Target Stores. I don’t foresee any recent edition being truly “collectible”, because they have been printed for long runs and most stores seem to have 1 or 2 copies of 1940 2nd edition at this time. The AxA minis appear to be somewhat collectible, again they were massively printed but they have been out of print for several years and there is a community of people who still want select (ships). I don’t believe that the “land warfare” AxA collectible game was nearly as popular.
When a game is active, new editions will push out old editions, such as the Pacific 2000 and Europe 1999 boards. I see very little demand for these as well, because they are obsolete rulesets. However, they do have a different set of “hard” glossly plastic sculpts that are different, and the games are indeed different.
Its different for the Dday, Battle of Bulge and Guadalcanal versions. Those are completely different games and they were printed for a short amount of time, 10 years ago. They are collectible.
As far as the Global Boards go, they are the premiere product. They should stay in print for a while. However, the game appears inactive (this can change at any time) right now, so eventually they will run out of the most recent print of these and the decision will have to be made to print 20-30K more…which I don’t think they will make (Argo points out many recent editions contain disappointing properties and re-issues).
So, to conclude, Global boards may grow rare in the next couple years, or dry up, but I don’t see them as going up in price much. If there is still “fulfillment by amazon” and a 20% discount, that is a sign that they have many copies at the warehouse. Once only individual sellers are pricing the game at %100MSRP, its becoming uncommon. The naval minis and “theatre” games appear to be the best targets.
