A whole new solar system with 4 planets (e.g Keplar 2249-C) or the Andromeda Galaxy (the Milky Way's twin galaxy) with a couple of planets and we'd have to go through a whole new screen when traveling there like a cutscene of our guardian passing through a transdimensional realm that allows quicker travel between solar systems/galaxies rather than a ship going towards a glaring ball. Destiny II or whatever it's going to be called better be a traditional MMO that also adds manual traveling to other planets, like getting in your ship and traveling to the planet and having to land anywhere manually, could you imagine the thousands of players in outer space just roaming around.
