Think I'm right on board with the reviews. I jumped at the PC version and luckily it ran really well once the settings were tweaked. I spent roughly 90 minutes in the game and visited 3 planets and one space station, killed two sentinels, found an outpost, learned the word "interloper" in alien... (I posted screens in the PC performance thread of all three planets, plus one deer monster for anyone interested).
It's definitely not for everyone, I was bored after planet one, the traversal is pretty slow with the waypoints spread out, the game is painful to start due to the multitool overheating constantly, and the stuff I was running across wasn't really that interesting. Additionally, I could see components of the first planet (both the creatures and the environment) in the second two. The ship navigation doesn't feel compelling at all, which was one of the things I was hoping would hold up.
I know they're going to work on improving this, but for $60 I can't justify holding on to it.
