So many games, as you progress through the story, have inns or certain services that cost money(of course). What bothers me the most is as you traverse through towns later on, each commodity differ in price, usually increasing as you progress; i.e. the first village you enter will require you to pay 10 coins to sleep at their inn, whereas the last village you encounter in the game will require 2000 coins to sleep at their inn or using a caravan in village 2 is only 20 coins whereas a caravan in village 9 is 400 coins.
Do you think prices should increase as you progress or should each town and village have varying prices(based on certain factors such as an upcoming war, during a war, certain disasters, etc), such as a poor village inn is only 20 coins, but an inn in the rich area of a city is 300 coins and a small village you encounter later on in the story is about 40 coins.
