I've moved this to development, as I personally feel the idea of creating a food resource for adventuring is excelent, and would make a great book.
It could be generic, or system specific, though I think the stats should follow the 10' Pole model which is quite generic, with a few refs on how to use it with other systems.
There is just so much scope it is hard to decide where to begin, real recepies with a twist or too, food lists by culture, status and need, this could if handled correctly become a realy useful tool for and GM.
The idea is Grinnens, so what we do with the outcome is down to him, a Guild article, a saeable PDF book, a free resource, whatever, though if done well enough a paid for PDF would be a feasable option.
I want to devote some time to this, but i have little so Grinnen, you move it along, and when the dust settles, I'll design the book.
