/ DESCRIPTION:
/ Different trading posts have different items.
/ Merchants cannot be cheated, but they can be dishonest
/ themselves.
/
/ Shields, swords, and quicksilver are not cumulative. This is
/ one major area of complaint, but there are two reasons for this:
/ 1) It becomes MUCH too easy to make very large versions
/ of these items.
/ 2) In the real world, one cannot simply weld two swords
/ together to make a bigger one.
/
/ At one time, it was possible to sell old weapons at half the purchase
/ price. This resulted in huge amounts of gold floating around,
/ and the game lost much of its challenge.
/
/ Also, purchasing gems defeats the whole purpose of gold. Gold
/ is small change for lower level players. They really shouldn't
/ be able to accumulate more than enough gold for a small sword or
/ a few books. Higher level players shouldn't even bother to pick
/ up gold, except maybe to buy mana once in a while.
