Only for that player. That gold he's getting isn't coming from an NPC, it's been given by the person making the purchase, with gp that was already in the game. That's a very important thing to remember; a person can increase his wealth, even though he's decreasing the total amount of gold pieces in the economy (and gold pieces are how people express their demand for an item, and demand is one of the determining factors on price, the other being supply). Likewise, a person can decrease his own wealth, while still increasing the amount of gold pieces in the economy; example: Alchemy and High Alchemy. -- To better illustrate what I mean, let's say that in the entirety of runescape there are 100 people, each with 10m in gold pieces (not in total worth, but in actual gold pieces). That means that the total number of coins in the economy is 1b coins. One of these players manages to get a rare item valued at 8m by the economy. He also expended 2m gp due to needing to recharge his weapon. 1. Upon spending that gold, it leaves the economy, and the total amount of coins in the economy is 1998m coins 2. Despite one player now having 16m in coins and another player having only 2m, the total number of coins in the economy has decreased overall. --- So, to summarize; The amount of gp in the game increases only if the transactions being performed increase the number of gold pieces that can be possibly spent. A transaction with another player does not do this. An item drop does not do this. A gp drop does do this. High Alching does do this. Selling items to npc shops does do this. You are not "converting something into gold" by trading with another player; you're exchanging your item for their gold. No gold has been created or destroyed in this transaction. Alright, I see what you meant now.
