In your ship there is a computer at the back (to the right when you enter). That computer contains a digital investigation board - y'know, with the photos connected by string and stuff.

Once you find that, the game really starts to make sense. It's not a walking simulator, it's an active crime scene. I won't say what "crime" (and I'm being somewhat metaphorical here), in case you didn't play long enough (about 12 minutes after you encounter the statue in the museum) for The Event to happen (The Event will make you think very differently about what this game is, but I can't talk about that. We don't talk about The Event). But that's basically what's happening. There's a problem, and you have to solve it, but to do that you'll have to unearth years of lost history, piecing together the story of an alien civilization that has visited your star system. The gameplay is primarily about exploration, trying to figure out where to find and how to get to the clues you need to put everything together. Slowly, the murder board fills in, the pieces connect, the list of suspects narrows, and you spiral in towards a genuinely shocking and heart wrenching conclusion.

Does it get good? My friend, it gets EPIC. The sheer scale the plot operates on is mind blowing. The ending destroyed me; easily one of the best stories I've ever encountered in a video game.

The flight mechanics are intentionally fiddly. You will get used to them eventually. The gameplay is exciting, sometimes terrifying, but don't expect them to like give you a gun or anything. It's a puzzle game, but the puzzles are never a fucking Sudoku. If you can handle that, it's one of the best games ever made.
