The idea is cool, but I don't understand how to lose or win.
I can put up any quest for any stat to max for 1 gold and make money infinitely.
The only way to trigger a losing state seems to be to choose to spend too much gold on a reward, but there is no incentive to increase the reward past 1 gold.
Is the goal to make as much money as you can in XYZ time?
Am I missing something?
