To be honest, I rarely look at D&D's economy and how it functions. I just assume that it does. And why not just assume? I mean, I playing Dungeons & Dragons, not Economies & Economists (though an Economist would be a fearsome Solo foe, no doubt.
).
Anyways, I don't understand why understanding the Economy of D&D is such a big deal to people. Is it really necessary to know how much money the farmer brings in each year, or how much land it takes to sustain a certain population, or the ins-and-outs of magic item trade, inflation, the king's demand for them, value degradation?
I know that to a DM, his/her world means alot to him/her, and that they wish to make it as immersive as possible for the players, but why is it necessary to "recreate" everything that's in our world and explain in detail how it works. Most people just play D&D to have fun (and I don't mean to be "munchkins") and adventure with their friends. To escape the realism of this world and all of its problems, and imagine a place where you can bash an obvious villain (or someone you just don't like) over their heads and be praised for it.
Am I wrong?
If the farmer has a bad year, just increase the price of farm goods a little. If war plagues a nation, increase the price of war goods a little to signify scarcity and inflation. It's not really necessary to know the exact formula as to how this occured or how it is going to affect the world (not to mention cluttering your game with "%'s" and "ratio's" and "Zzzz's"), only how is it going to affect the players directly.
Idk, this whole economic debate seems rather pointless in my eyes.
Just my $0.02.
-As a side note, the new treasure system looks pretty cool, though I will reserve judgment until I actually see it in play.
