Who would leave resources after they cleared a dungeon? I always thought this part was forced.
"Yeah we killed the boss!"
"Woot!"
"Now remember guys, don't get too greedy with the loot. Leave some for your competitors"
"Right boss! "
"Hmmm.... Do I really need 5 apples.... The quest only calls for 2 so i guess I'll leave the others here even though they would sell for 100s of gold."
"Good thinking Phil. Don't want to be like that Hoarder Freak who keeps making money while not leaving anything for his competitors."
"Yeah what a dick."
