There’s some zero G combat areas you can come across. Like other Bethesda games, the main quest isn’t where you have the best interactions.
Level up the ship building skills and turrets will kill in space battles sometimes too fast. I rarely get the chance to board and steal the ships unless I scale back and turn off weapons.
If you want to stay in the game, you can target planets and moons from the cockpit to travel without opening up the Star map. Only scanning has to bring up the map. Random space encounters can be more enjoyable than some of the Fallout 4 ones.
