How about this ladies and gentlemen...
What if there were 2-3+ island out there for players to chose as their own. Once you select a island you can build and expand your own house etc. The player housing islands would be privately instanced so when you sail to it your island gets loaded. Just like in so many other instanced games now days.
If you are on a boat with a crew and sail to one of these islands and two or more crew members have claimed it. You get a vote screen on witch one to go to once you sail close enough.
In what capacity this island and player housing would have I dont know. It have to be balanced correct with the outside non instanced world in terms of PvP etc. But the possibilities are many. And I think it could be a fun thing.
