I agree with you, RGS, but NOT if they add in long-lasting food that is actually long lasting. That's what I was talking about, with the hunter types and recruits and such still having food. It's just all...rations, cured food, salted meats.
Nobility and rich merchants, on the other hand, will have the means to say 'I want tasty delicious food.'
In essence, I don't think it breaks the game so long as those longer-lasting items are made. It just makes it so that different people eat different kinds of food. I, the fruit forager, will be hawking fruits. Nobles and such will buy it, because they are rare and harder to find. But I will lower my price as they start to spoil. So on and so forth.
The issue I have with the thing is its incomplete state (however, they are making adjustments -very- quickly, which I think is a testament that they realize the fragile, undesirable place it's at right now), and the decay rate being much faster than what I'd desire our food items to have to go through. We didn't need extremes in this regard to get what we wanted out of it in that discussion. Where we are now, I consider a sort of extreme until more work goes into the preservation, or more work goes into the individual foods themselves (i.e. Like I said in RAT, bar food gets cheaper and decays quickly, while rations are more valuable and last a -long- time, as is the case when you prepare for long trips).
