Played it for a couple hours. Has a lot of game-breaking issues (it's pre-alpha), but it's really cool. Like Legos and No Man's Sky (but much better/more like what it should have been).
Issues I had:
AMD FX CPUs have issues. I had to play the game with no sound to fix an unplayable framerate issue. (-NOSOUND launch parameter). Okay, so it's playable at this point.
Playing a game with a friend, we both crash. Didn't save. Start that save (it saved after I landed and that's it) again with friend, but it had severe issues like no recharging power, 2nd drop pod existed multiple times, friend couldn't interact, etc.
So we load up his already-progressed game and play that. Lots of fun, but glitchy. Playable though. Then a sand storm comes. I start driving a rover into it and crash. Now, every time I connect to him on that game it just crashes. So the game has save-breaking issues I guess...
I ended up refunding it, but I'd gladly get it again later. I just wish they had tested it better before they released it. Or a public demo maybe? I have my hands in so many early access titles, this one just rubbed me wrong I guess. The game itself has a lot of promise though, and lots to do already.
