It has the skeleton of a great game, but it's poorly implemented, and the main storyline is just lazy writing.
What makes me especially sad is the interviews I've heard from the developers stating that they had originally made for more of a exploration / survival/base building game but that they damned everything including space combat down, I would say to the point of no longer being fun or challenging to play. I think I'd rather finish a Mass Effect title, or playing Outer Worlds again than finishing it.
Who knows maybe they will get it right with the expansion pack ...
