From what I understand, part of the problem is that realistically, many things would be priced under a copper but we can't do that because there's no lower unit of currency.
Well, you handle that the way we always have, I'd imagine - by buying/selling these items in batches.
I even poked at the code earlier to see about updating the whole "That's not even worth my time!" thing to comment on how the item is worth less than 1 cp, so sell more.
Right now, assuming what my PC ate was a 4 oz fillet, it has no noticeable affect on hunger levels - in other words, you can eat a 4 oz fillet without feeling as if you've eaten anything at all. Now that's plainly out of whack.
That's beholden to the current breakdown in hunger levels and how they divide. Peeking at the code earlier we have ten levels from "almost starved to death" to "absolutely stuffed" so with how that divides out the fish fillet might indeed exist between two of those levels so you wouldn't neccessarily see a change in your coded level. However, if you'd eaten the fish fillet with a side-dish of some sort I'm guessing your would have.
Which if the concern is people getting more of an inkling on things, we could add more level names (maybe 5?). So you'd see changes more often to give a better feeling what you were eating was actually helping. Ultimately, the levels are simply a reflection for the benefit of the player, code simply pays attention to numeric values.
Of course, even then, obviously we'll still have items that wouldn't neccessarily raise you an entire level when eaten individually.
The aim of the firm (Arni) is not to buy as many products as possible from suppliers. The aim of the firm is to sell goods and services and make a profit. Arni should most definitely be buying for peanuts and selling for slightly more.
Arni has dutifully served an expanded purpose while other systems were/are being put in place. No doubt he'll be scaling back on his ravenous desire for raw meat in due time.
Please burn your resident economist in a vat of oil and hire me instead. I'm volunteering my services for nothing more than the occasional cheesebun.
Most of these prices were set by me before said resident economist was in his current capacity. Again, I did it, so direct ire towards the appropriate source.
However, if you are serious in the desire to assist in some capacity and provide ideas, PM me and lay out what you are interested in.
