If there were an economics portion to the game, I think it would be best if it were just an automaton running behind the scenes. The idea of rationing supplies -- not being able to fire that full 8-shot spread every time because you only have 12 fish -- appeals to my romantic side.
Devoting a player or two to run the economic side of things seems like it would be a little tedious... not to mention that this is a combat-oriented game to begin with.
Ponder complete... well, mostly.
Cheers all
