I probably don't have anything to say that hasn't already been said multiple times here and elsewhere.
I finally let 3.0 on to my machine and fiddled around with it for about 20 minutes. My system is merely a 6-core i7 running at 4GHz with 16GiB RAM and an NVIDIA GTX-970 (the only "weak" part of the rig). This machine happily tears through just about every game I've thrown at it.
...And boy is this thing choppy. Just walking around Olisar has the disk thrashing it's brains out, presumably as it's loading assets. I didn't even bother to fly my ship; I walked around Olisar, then EVAed from one half of Olisar to the other.
It seems they've spent all their time polishing the visuals -- everything does look rather more impressive. There was an interesting "sheen" on the glass of the space ships that wasn't there before. A nice detail, but utterly insignificant to game play.
You're started with 5000 aUAE. Available missions don't seem to offer more than 200 aUAE or so, which feels grind-tastic.
Previously, when you looked at something in one of the stores, a description of the item would appear. Now all you see is an invented brand name and a price. "Um, what is this, and what does it do?" are kind of important questions when looking at armor, space suits, and spaceship parts. Shopkeepers repeat the same lines of monologue far too often.
The clothing store is still a complete waste of time and space.
Saw a couple of NPCs stuck behind planters, chairs, and other random bits of geometry.
Certainly there has been an attempt to make things more "realistic." Your EVA suit now has a limited O2 supply. You can become exhausted by running everywhere, depleting your O2 supply more quickly. Definitely realistic. Also: No damned fun.
I actually became comfortable flying the Aurora ES around in the previous release. But I'm anxious they've changed all the flight controls and dynamics, so I'm afraid to take my ship out for a spin.
All in all, there's still no "there" there. It feels like a dying amusement park -- the only reason anyone is there is out of sheer habit.
