(disclaimer: tounge-in-cheek post)
I've been working on it the past two years, unfortunately since I am not a GM, or even have access to the DR codebase, I've been doing all my code in C++.
Now the hard part is actually integrating it into DR itself, and convincing Bubba and other GM's to allow me to do so.
Nevermind the fact that I have the actual system coded, and not any actual data points, so if I activated what I have now, you'd simply be left with "A grain of sand" as a commodity, with very little value; even though you could buy/sell that to your hearts content. Problem being there would also be no market fluctuation, since those values are left unset.
Even Worse is the fact that I do not account for Muspa'ri having more Sand than most other places.... Hell Aesry would have as much sand as Muspari, and I don't even have shipping trading working yet. :(
(Yes, I am not a GM right now, nor do I have the time to actually be one; even though I do feel my programming knowledge would be an asset if I did apply as one)
