I think currants are misplaced in the world of Ur. It is the only thing adopted from real life that does not fit very well in Glitch. It stiffens creativity and imagination (items become a number instead of endless possibilities and players are focused on a singular activity to increase this Metabolic).
The auction house can be transformed into a market, where people formulate their offer and demand.
New players receive tools and other items as reward for quests (or as utilities at the start of a quest).
Change to vendor mechanics (and possibly donation mechanics)
Would another item (beans or ingots) emerge as some form of currency?
And what are other effects on the game mechanics?
What do you think, Glitches/Glitchen(s)/Glitchians/Glitcheroonies?
