orangefruitbat said:A greek talent is about 57 pds. In DnD terms, there are 50 coins to a pound. So 120,000 silver talents translates into:
57*50*120,000/10=34,200,000 gp. So, if we assume that Alexander the Great was a 20th level fighter, he clearly had a monty haul GM!
You are forgetting that the purchasing power of silver was a lot higher in the real world throughout history than in D&D. If I recall correctly, the wage of unskilled labour just before Alexander's big experiment in monetary expansion was about a drachma or so per day. A drachma was about 1.8 grams of silver. A D&D SP is 9 grams of silver. So the value of Alexander's windfall was about five times what you calculated.
