Changes

Two main differences from the minimal system. The first is that much (or most) of the money that goes out is returned to the game through the king. This reduces the need for bought silver to keep the currency stable.  The second is that this money is granted to size 10 villages. Anyone who buys and pays upkeep for a homestead or size 5 village is essentially subsidizing the larger villages. The subsidy might be on purpose, so that people pay for the more expensive and higher upkeep size 10 villages. Of course, this also makes it more likely that people gather in villages, which might increase player trade through specialization - but that is just a conjecture as lots of social factors kick in.
