They never said "star trek in space" because, first of all, that's redundant, and second of all, would invite lawsuits. I'm not even necessarily saying that they're copying star trek in any way.

I'm using Star Trek as an illustration of the positive sci-fi genre and the tone they were putting out in their marketing. No, its not literally star trek - but unlike their other titles that are either distopian sci-fi or a semi-dark epic fantasy, this one has a more positive tone - there's a sense of hope and compassion that even persists in more distopian areas like the well, cydonia, ryujin, and ebbside. And furthermore, the main story's focus on the excitement and wonder of exploration, and traversing the unknown, is a love note for Star Trek and all the sci-fi novels strewn about the environment.

And though this clarification is quite separated from it's context now, I only brought this up to say that this game is far more hopeful and optimistic than their previous games and I feel like their marketing illustrated it quite well. And the reason it matters is beacuse the lack of the "darkness" and "grittiness" you are looking for can be explained by this difference in tone.
