In an online game, you should be able to get away from people; and conversely if you want high player interaction the servers can just be player dense (20+). If the islands is structured like AA, then the servers will be too player dense; and seeing how the current player base seems to hate random pvp I don’t think that’s a good idea.
Open Test 3 really wasn’t that large, and I’m only giving that example for the highest end. I’m not advocating for that to be the average island size. Definitely not.
