DISCLAIMER 2: IMO PRETTY MUCH EVERYTHING GAMEPLAY NEEDS SOME REWORK
No loading screens. This is the first game that delivers on it with no bs. I just love walking around, landing on stuff. Landing on a L ship with my Discoverer, walking about to poach their crewmember for a manager and standing on it's bridge as it docked with a station

I love being taxi'd around as I gawk through the windows. I wish they will add proper "designed" ships later on, so you could get a ship with an observation deck. I love that the cockpit windows have those black dotty things around their edges like some IRL vehicles do.
I love the space suit. It just gives me goosebumps. It's perfect.
I love the mish-mash of different transport devices, all the (super-)highways, accelerators and jumpgates mixed together
The map and the station builder, ship assignments to bases, station managers are a nice thing
It's just so much fun to fly.
The feeling of scale is there too.
I really like (im extrapolating here) how moddable the game will be
I'm just so mad because I want to play lol so badly
