Expansion makes the game truly beautiful, a visual marvel. Comes with a price of very high system requirements. New gameplay revolves around mining minerals on planetary surface, then synthesizing them to create buffs for your weapons, ammunitions, ship systems etc. There are some missions but they pay next to nothing and revolve around finding some emitters in bases or something along those lines. Rest is pure fun, planets have variable gravity which affects your ship and SRV which means they will behave differently on every planet. High gravity planets are great for racing, low gravity are great for making canyon jumps. Extreme gravity will make it very hard to fly near the surface because it will constantly pull your ship down and you'll need to compensate with thrusters.
