Odd game...

Hi all, fired up a new game yesterday, playing as Venice on Pangea plus, all is fine except that maybe its not odd at all, instead being me that dont know exactly the difference between normal pangea and pangea plus. Theres the huge landmass as always, then an archipelago where most of the CSs stay, not a single one on the mainland, so is it normal? Can a kind soul tell me what makes the two maps different? I suppose the same would apply to continents and continents +?

Thanks in advance.

Pangea Plus and Continents Plus don't have City-States on the "main" continent(s). Instead, City-States are situated on their own islands or island chains, to "free" the space on the "main" continent(s) for main civilizations.
