Map guidelines
While the next section (Map Making Vision) will explain how to physically get started building your map, this section will describe guidelines to keep in mind while you build the map.
Copyrighted Works
You should be careful not to violate any copyrights unless you have consent from the copyright holder.
Border overlap
It is recommended that the borders of territories in the same bonus overlap, whereas the borders of territories in different bonuses should be adjacent.
For example, take a look at part of South Africa in Grundie's Earth map:
Connection Lines
If you wish for two territories to connect, but they aren't physically touching each other on the map, it's necessary to include a line on the map so that players can easily see that they're connected.
