The Price of Ice
The Market Values for Ice appear to be illegal, since “Each substance also has a Market Value, which is different for each Moon.” and Ice is currently worth 9 Iron on three of the Moons.
As I read it, when Bucky was setting up the substance values, whenever a random duplicate value was generated, it should have been left as a hyphen. I’ve gone ahead and changed Ice on Ganymede and Callisto back to hyphens. Anybody can undo this if they disagree with my reading.
Bucky:
I had interpreted it as each Market Value being tracked separately, as opposed to “which has a different value for each Moon”.
