I'm sure we're all aware of Jupiter's existence in our Solar System, if not then you've been living under a Dwayne Johnson for god knows how long but anyways, I've always wonder at the idea of being able to visit the gas giant planet, Jupiter. Now it hasn't been proven whether or not Jupiter has a surface and its safe to assume that it doesn't, it will take a good while to find out if it does or not. But exploring Jupiter doesn't necessarily mean that there should be a surface, instead what I had in my head was making it sort of work like Star Wars and Cloud City. I'm sure we won't get any new planets in any of the expansions but its wishful thinking.
