Played it for about an hour or two (since I preordered it on PC, have to wait until Friday to really dive in.) I'm not too sure what I think of it so far, but I only played a short sitting on my brothers PS4 copy until he kicked me off to play it himself.
The game looks good for what it is. Some beautiful environments and some ugly textures. Didn't really expect too much in this department.
The survival elements are tedious and take away from the game in my opinion. Not a major complaint but having to worry about multiple different fuels for your ship and mining laser and things for your exo-suit and life support is annoying. I don't mind having some, but this is a little too much.
Inventory is bad. Personally think it's way too small (though you can upgrade this, not sure how much of a help it is). Compare to Minecraft where you can build a place to store your items and materials, a the start of NMS you have a small personal inventory and your ship's inventory is not much bigger. I suppose that's part of the "exploration" theme that you don't get too take too much with you but it would be cool you could maybe plop down on a planet, move into one of the empty outposts and store and build upgrades and such until you hit the skies again.
The inventory menu is also clunky imo. I don't like how all upgrades to your ship and suit take up space.
The soundtrack is nice.
Also pretty disappointed that Sean Murray apparently flat out lied about multiplayer aspects.
