I spent 1.5 hours in the game last night and have to say I enjoyed every minute of it.
The atmosphere is incredible, they have done an amazing job as far as that is concerned, it is incredibly immersive, it reminded me of certain films, like 'The red planet', Pitch black' or 'The Martian', the sound did an amazing job of making me feel edgey, I can see now why they have set the FOV as it is, because I found myself several times stopping what I was doing and spinning around, convinced there was something behind me.
My first planet is an eerie place, rocky with lots of canyons and deep gulleys, no signs of life, just rock formations and some plants.
I managed to get the required bits to fix my ship and so took off to find a resource site that had appeared on my scanner as a 5 minute walk away (I couldnt get to it as there was a deep gulley in the way).
The jetpack by the way is lots of fun to use, I'm looking forward to upgrading it and seeing what it can do, it feels great jumping into gulleys and hitting the jets as you fall.
After flying for a minute or so I noticed some buildings, I landed on the edge of a nearby hole and investigated, inside I met my first lizard like Alien, in exchange for carbon and something else I forget, he tought me a couple of words in his language, I also picked up some new upgrade tech blueprints for my gear.
I did not want to put the controller down at all, but it was 1:30am on a weeknight so reluctantly I had to call it a night, itching to get back on later and explore more of the planet.
Here's a pic of the buildings I discovered.
