In terms of things I'd say to encourage someone to play without spoilers, I think I'd focus on mechanics, like:

1. The game has depth to its locations that shows up on repeated visits. Expect to return with better tools/information to see new things. Shortcuts will reveal themselves over time.

2. There is an in-game tool that takes notes for you, hints at undiscovered content, and can provide on-screen waypoints to help you navigate.

3. Don't be too worried about your (avatar's) personal safety, or about rushing. Later there may be times where both might matter for your goals, but the game is designed to support trial-and-error.

P.S.: And if you're playing on a PC, know that there is one section of the game where you need to use your ship thrusters so very gently that it almost requires you to to use a controller.

2. Yes! The automatic notes are perfect for getting back on track without spoilers. "There is more to explore here."

		I know for some people it removes a sense of wonder and mystery, but as a completionist sort, I really appreciate "you found everything nearby" indicators. It means the game/designer respects my time as a human with (a few) other things to do everyday.
