I find it would be cool that some Skyislands would be bigger. Have some Skypean guards like we've seen in the Series.
Would be cool to encounter "God" as well. Make it a type of trainer or a Boss, maybe both depending on what the player decides to do.
There could be an event where Pirates invade Skypea and you defend. The same event could also be a 1% Enel appears.

I believe in the Patreon there has been said, that there would be possible to "recruit" helpers of the same faction or smth.
After such event as I mentioned, couldn't there be like a "relationship meter" or smth to recruit certain types of Skypeans? (Or just the fighter types)

Could there also be added a new way to go there without us having to get 200 blocks to reach it?

Thank you for your time and it was fun

A large series of connected islands would be dope, the current sky islands are pretty lame

Actually like the idea for bigger sky islands

A skypean dimension was at multiple times planned however even now, it'd just be too empty, as Im against anime npcs spawning in the open world (be it even a different dimension)
So all there would be is endless sky oceans with islands, traders, villagers and weather wizards, maybe some unique traders, cheaper dials and open world dial spawns sure...but still overall empty.
So while im not against it per se, I just don't see any good reason for working on it right now, as its a pretty big time investment to begin with.
The raids and relationship meter do help but...is a clone of how vanilla villagers work be enough to make it worth adding is the question...Enel spawning there is 100% out of question tho.
