After reading this in the noctis thread:
If I implement a good underwater environment, then players can use a submarine as well.
Just wanted some more info on that, I think that would be an amazing way to make the game even deeper (pun intended)
Currently water worlds are extremely boring, once you penetrate the thick cloudy athmosphere there's just water everywhere. Of course. but when you go under water it's pretty much flat everywhere. It would be awesome if the bottom of the bodies of water had different styles and rocky regions and pretty much looked like the bottom of the ocean, with caverns and such and even "corals' on ocean worlds with life. That would be awesome.
What do you guys think?
