Assumption 1. The game can tell how much gold is on the shard. Now take the amount of gold dropped on monsters and make it a percentage of all the gold in the game. Now take the cost for NPC items and make it a percentage of the total gold in hte game. Assumption 2. The game can decrease or increase loot drop gold based on a formula. The game can adjust prices up or down on NPCs based on a formula. Please lets have a debate. A nice one. EDIT: Woops wanted my own thread. Posted wrong place.
