/ 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.
