I played through a good chunk of the tutorial and so far I'm in the disappointed category. I'm going to give it some more time, but there are a few things which just aren't working for me.
The first is the highways. I didn't like the gates in the previous titles. Just let me jump to coordinates and freely navigate the immensity of the galaxy, please. But I assumed they were a necessary and not too intrusive limitation. The "highways" take intrusive to the next level. They're like glowing green tubes snaking all over the place. And what's with the whole slipstream mini-game when you're inside? It's silly. I want to feel like I'm navigating a ship, dammit. And why is travel inside these "highways" so slow? "Leave highway in 200 kilometers"? And then it takes ten seconds to go 200 kilometers? I guess it has to be slow to make the "game" of using the w-a-s-d keys to jump into a faster "slipstream" meaningful.
I second what CottonRabbit said about the cockpit. But I think it is also the environmental design. All the initial locations were extremely cluttered with asteroids, ships, stations, highways, and you're viewing the whole thing through this fairly narrow strip of windscreen. It feels very closed in. I didn't get even the least impression of the vastness of space. Actually felt more like I was underwater. I guess it wouldn't be bad if the cockpit was somewhat functional, but basically all that view real estate is occupied by static images that a) don't look all that good; and b) don't do anything.
The environment must be gorgeous, but how do I look around it? Stop my ship and pivot? I couldn't find an external view camera. You can't even look around the cockpit itself while flying, as far as I can see. Maybe I'm missing something here. They can't have failed to give you some way to look around, can they?
Pretty damn meh for me so far. I will give it more time later. I don't want to write off the first new space title we've had in years too quickly. But initial impressions are not positive.
