-There are no loading screens as you move through the ship
-Galaxy map returns but rather than piloting a mini ship on a map, it is more immersive, you select a planet, the game gives you sense of traveling towards that planet, and when you back out, you're immediately at your destination
-You don't pilot the ship manually, but it feels seamless as you go from planet to planet and see them from your bridge getting closer in the window
-They wanted a seamless experience from picking a planet to walking down to your cargo hold, hopping into the Nomad and landing on a planet. There is a landing sequence and you get off the ship. No more loading screens and instantly popping up on the surface of a planet.
Except for the lack of manually controlling the Tempest, these are big and important things for me that I'm happy to hear about. I hope the exploratory nature and ambient synth are up to snuff, that's all I need to be happy.
