A Title Much Cooler Than Anything on the Old Site
One thing I like about Frog God Game's adventures and setting books set in the Lost Lands is that every settlement has a stat block that give some demographic information and the most you'd be able to GP available to make by selling items in a month.
- Economy guidelines - Poor, Average, Rich areas should have varying costs and availability for goods and services. Include that in the PHB so the players see it and can make decisions based off that information. This should also include "endgame" money sinks. Feel free to include a bold line that says "DM discretion", but player facing is a must.
Sime light rules and suggestions for creating a settlement with stat blocks would welcome in the One D&D DMG. Basic rules for building a strongholds and settlements would be nice as well, but I think that more detailed rules would require a separate book.
