I posed this question about a year ago in regards to my Rocky. I’d been hearing for years that there were less than 100 fully operational Rockys out there, but there’s no way of quantifying that. Someone posted a good equation about how to determine the probability of scarcity based on the age of the game, production run, etc. but I can’t recall it exactly. You can easily find it on my thread “Question about the rarity of Rocky”. There have been recent comments on it so it should be fairly easy to find.
