Though everyone think of Caribbean pirate when it comes to pirate theme, which is well represented in the game, I'd like to see other theme of piracy in game for new content
Mediterranean-theme sea with desert/oasis/arid biome and north african style building. Featuring trans-desert trade, sandy ruins or old tomb to loot. Maybe introduce "ship of the desert" if there is vast desert present. Barbary pirate inspired tall tale will be nice additions, too
North sea theme with fjords, taiga, dense alpine forest, snowy biome and Nordic wood structures. Focus on coastal settlement raiding or landmass with navigable river for inland settlement raiding.
And of couse it will comes with middle-eastern and viking style cosmetic.
Diversity of scenery is always nice in a open-world map game like this. Just some food for thoughts.
