I was really excited for this game, followed by having to temper my expectations after the initial impressions hit (especially the hit-or-miss quality of the PC port), but I bit the bullet and picked it up last night. Only got to play about an hour before we switched over to Olympics, but here's some thoughts...
On the one hand, I really like how the game is hands-off in explaining things, giving you a chance to explore and discover at your leisure. On the flip side, there's something to be said for those annoying tutorials which introduce your HUD one piece at a time. My starter planet (second starter, actually, since I lost my first one restarting after changing PC settings) was littered with giant gold deposits, so I thought "Great, better stay here." It was cold though, and I didn't fully appreciate how my hazard protection, life support and health related to each other. Consequently, at one point I realized that I wasn't actually burning through life support (which I had ample resources to refill), but I had exhausted my hazard protection, had no materials to refill it, and was down to a single health unit. I lucked into some Zinc and found a place to wait out the night, but I feel like my character actually would have known that he was about to die, whereas I didn't realize it because the game was so hands-off in explaining things that I completely missed where my health was tracked. As it stands, I'm still lost as to what most of the symbols mean, and the next "mission" along the Atlas path took me to a planet a million kilometers away, with the mission marker being underwater in the middle of a giant bay. Balls. My luck I'll be attacked by a space shark.
As far as the PC port and problems people were having, I had some serious hitching when I first loaded. I disabled vsync and AF ingame, set the FPS to max, disabled shader cache in nvidia control panel, and now I'm running flawlessly at 3.0x DSR on 1080P (don't remember the exact resolution as listed ingame, but it looks a lot crisper than 1080P). I5-2500K @ 4.4GHz and a 980ti, 16 GB RAM running off an SSD. There's still lag when leaving/entering atmosphere, and the terrain generation is blatant, but I expected that and it doesn't change my opinion on the game. I'll make sure to try enabling triple buffering when I get home, and maybe look into forcing AA through control panel since people are reporting ingame SSAA seems broken.
I haven't really played enough to say too much about it, except that I'm still confused by how crafting works and I'm a little bummed that it hit right during the Olympics when my TV is tied up with other things, but overall I'm really optimistic that I'm going to love this game. That sense of wonder when you first get your ship up and running and blast into space? Sheeeeeiiiiiitttt.
