Imagine hollowing out an entire mountain and building a base hanging onto the walls of the now huge Cave and making the water flood the floor of the cave, deep enough to sail ships inside... Well... Nope... We need the water to be able to flow to new areas before that can happen...
Devs, please make water Physics so the water can flow
And huge procedurally generated multiplayer maps... You would be able to rival Minecraft with this game if you did, there is such a huge untapped potential in this game
