I had been just going by the map overview, so I figured out how to get into the map editor, and I was totally wrong. Definitely 4 unconnected continents.
Also, I figured the map was totally symmetic, and it is for the most part, except for one thing: moisture. The northwest and southwest starting positions are actually vastly superior to the northeast and southeast starting positions because better situation for rainfall.
Is anyone well versed enough with the map editor to fix this rainfall disparity? Also, I would definitely prefer the map be circular rather than flat. Finally, would we want to use the map editor to join the continents like I mistakenly though they were already?
