The world map was created by hand to make it look plausible. The tool used was Excel, and the conditional formatting tool was used to display colors intuitively.

Originally, I thought I would have to create a world map generator and have it be generated procedurally. I scaled it down because it was obvious that if I touched it, it would inevitably take several months and over-engineer it.

Like the affected games, each country has its own territory, which is bounded by the city or town it occupies.

Where there is a port and a road has been paved, travel time is short due to low mobility. So you can save food.

I haven't created any monster generation areas or dungeons in the field yet.

I roughly set up the village's concept, resources, purchasing power, and production power. 

I start journaling today so I don't give up on the sheer volume.
