1) One of the sections is designated "Eastern" (I believe it is Laurasia). There was no geographical reason I could see for this. Does this reflect a cultural difference (like the silliness of distinguishing Europe and Asia as separate continents, instead of Eurasia)?
2) Antillia is at the end of quite a fetch of land. General climate might be dry, even semi-arid.
3) What is the name of that super-gulf that looks like a fork (this might help wet Antillia's climate, BTW)?
