Now, I'm not exactly sure if we could call this a game of three ore monty, after all he is saying that on average he receives a blue gem with every stack of ore. But it brings up an interesting idea. If there are possibilities of failure with prospecting, can you ask for tips for such a service? And if there is a gamble, could there by extension be a bet on such a risk? I don't know if this sort of thing is frowned upon by the devs or not, but I would definitely be curious to see how a betting system would work within the game. Not with actual money, but rather with virtual gold.
Is prospecting more gambling than not? And if there are assumed risks in the game we deal with, would you ever consider betting on them?
