After reading all 50 in one sitting I realised something.
This seems to take place in some sort of weird freeky universal system that combines everything into one. I already notice Dungeons and dragons, Call of Cthluhu (the good one), and possibly Shadowrun
Also WOW did Harry Potter's sanity start low if he already is getting halucination effects after one popscare.
Short-term, infinite gold seem all good and dandy.
Long-term, infinite gold might not be a good thing for the economy.
I bet the DM is sadistic enough to inflate shops & service prices depending on how much gold the players have
Actually you see Dungeons and Dragons unlike most systems in existance has a universal constant that sets the prices of several objects. That being Magic.
Want to make a +1 sword? well you will need 1000 gold worth of materials.
Better yet even if you say "Well you can't possibly use 1000 peices of gold to make a sword" the system has you covered there to with the ability to transmute gold into more valuable objects.
So in essence the only thing of value would be the labour to create those items and EXP (but the system ALREADY ignores the EXP required to create most objects for NPCs as it is. Yeah Dungeons and Dragons doesn't make any sense onto itself and a lot of the plotholes have to be explained away by the DM... such as "why isn't every PC a level-1 commoner multiclass?").
This would mean people would have unlimited charges of any spell. Food and water... HECK Hero's Feast.
So it isn't like our economy where printing an infinite amount of useless stuff would bring doom on us all. This is Dungeons and dragons and gold has an infinite number of uses.
