Re: Discussion Zone
I'll answer backward.
You begin with just the gold - so, yes - you will need to buy Food and the like, unless you intend to be scouting Plains or buying from Cities early-on.
Regarding Attitude & Costs.
Attitude only changes the COST, not the QUANTITY. (at least not directly).
It appears to change the quantity for resources - because of decimal places. Since the game doesn't allow decimal place gold values - because it's just too much tracking: it's easier to enforce a certain "amount" of minimum trade.
Thus:
If you enter a new Settlement, and are Reviled with it, but, you want to buy Stone: you would pay 1 gold for 1 Stone.
However, at Standard rates; you would pay 2 gold for 3 stone (thus, it really is only changing the cost.)
Regarding other items - I will find a way to get them all "charted-up". One of the advantages of the wiki was being able to 'slice it up' a little more neatly, at the cost of having to click all over RPOL to find the information.
But, it will get up there.
