Europa is known to have an ocean between 30 and 60 miles deep under the ice. This would be an excellent addition for people who like to build underwater bases but cannot find oceans deep enough to make them truly huge on Earth.
The surface would be ice, with snow mountains (and constant snow falling everywhere) while the ocean underneath would be around 100 units deep, with a sand, clay and gravel seafloor.
The best additions for this would be making the space suit work properly underwater, and a small 3x3x3 one man submersible which can be driven like a boat. This would afford a practical way to explore and to move between underwater colonies built either on the seafloor, hanging from the ice overhead or hovering neutrally buoyant between the two like a space station.
To simplify life support this planet should have breathable air. This way you don't need the goofy life support machinery creating giant air spheres underwater. Because of how they're built, underwater structures already cleanly hold air inside and water outside. An ice moon with breathable air on the surface is unrealistic but so is Minecraft in many ways.
Thoughts?
