Flew all around a few planets. I couldn't see the sun, there were no moons, no barren planets, other planets in the solar system looked like they were closer than our moon. Other bodies didn't seem to move in the sky.
The generation is really flat and boring, I didn't see any mountain ranges or forests or any kind of interesting terrain features, all the planets I went to were just a smattering of plants all over and short hills as far as you can see. No cliffs, nothing that stuck out. I figured it'd be fun to be Spaceman Spiff for a few hours but by the second or third planet I already felt like I'd seen them all.
It's interesting - my starting system has been quite varied in comparison to yours. Started on a lush but highly poisonous world, next few planets were: a lethally frozen wasteland (nights would get below -75C, at which point survival time was a couple of minutes at best) with minimal vegetation and nary an animal to be seen (yet for some silly reason a lively trading post), a craggy and sometimes mountainous planet with sparse vegetation but a wide variety of animals clogging the place, and a moon that was a warren of small lakes and almost spaghetti-like rock formations and sharp ridges - small amounts of fungal vegetation and no animals to be seen.
A space station was nested between two planets, with the sun hazy and distant (because space fog). Of the 5 planets I spotted so far in the starting system, one had two moons and one had a single moon.
I'll agree that from I've seen the generation tends towards the mildly hilly over flat or mountainous a little too often and there's a distinct lack of forest, but not too bad for just the starter system. Hard to tell if the points of interest depend on the planet, but so far I'd bet they generally don't. As others had said, I'm a little astounded that there's no cockpit look. And I can't map actions to my mouse 4 and mouse 5 buttons.
Traded for a ship at a station and the pulse cannon is stuck at 0% - I can't recharge it, but I can shoot it forever. Haven't found any signs at all of a multitool upgrade, which is rather vexing. I also said no to Atlas, so I suppose I'll see how that turns out.
As a person who pre-ordered but tried to pay little attention to the coverage I'm feeling 'okay' about it. Runs on my system (680 GTX, i7-3770, 12 gig ram - so good but not excellent), albeit with some of the settings turned own. Downloading the beta NVIDIA driver (thanks for the link) seemed to make a significant difference.
