The outdated futuristic experience.
I've put in 150+ hours into this, but have uninstalled today (without finishing the main questline) after an escalating series of bugs and annoyances.
I gave the game the benefit of the doubt when it came to mind-numbing storytelling and weak characters, because I really enjoyed the gunplay, space battles, weapon designs/customisations and ship building. I actually didn't mind the fast travel too much initially either, but eventually it breaks the immersion completely. There's plenty to do, but not a lot of variety and many things seemed pointless - like cooking: there's basically no need to develop your cooking skills, as med kits are plentiful and waaaay more beneficial than a carefully crafted meal.
It won't take you long to realise that this is a re-skin of Skyrim or Fallout. The constant fetch quests and "Go here, talk to this person, then go back and tell someone what the other person said" work in a historic fantasy or the post-apocalypse. But here, in the 24th century, no one has WhatsApp or even a phone - so you are doomed to endless fast travel and long walks (without decent maps). I found myself tabbing through the conversations just to get to something interesting.
You will also come up against many, many restrictions: you're over-encumbered; your ship is too big (or contains too many modules); you can't have any more crew members; you can't sell your stuff because the vendors have run out of money; you can't be a real pirate because a) bounties will cripple you financially, and b) the loot you steal is miniscule anyway.
The bugs are also an issue. Here are my experiences: a dead colonist falls from the sky every time I unlock a new power; I constantly get the warning that I'm trespassing, regardless of where I am (and regardless of how many times I try the tricks people suggest to remove it in Reddit); my robot friend is always sitting on the roof of my ship (instead of inside where he should be); after ~100 hours of game play I started getting error messages saying I'd run out of space for save files (again Reddit didn't help me).
After 150 hours, it all started to wear pretty thin. So I tried to blitz the main questline to complete the story. After wandering around a boring NASA launch site (with just a handful of enemies I could easily overpower) I clicked 'OK' multiple times on the 'Save File' error messages (which had become a habit) and "saved" my game like normal. The following day I logged back in to find that my save file didn't work and now I need to go back to Earth and do the NASA mission again.
Instead, I clicked 'Uninstall'.
I might come back to this in a few years, when the modders have (hopefully) fixed the game. What a shame.
