No Man's Sky: 13 Little-Known Facts You Need To See
11. You Can Learn Alien Languages
One of the game's most fascinating yet little-discussed features is the ability to communicate with a number of alien races, but not without a little work. When meeting a member of a race for the first time, you won't be able to understand them, but using some guess work can possibly make your way through a conversation, or alternatively you can apparently use body movements and signals.
Conversing with aliens will make you more acquainted with them and "unlock" words to make conversing easier, while discovery of alien "monoliths" can also make you highly proficient in a given language.
Depending upon how deep this goes, it could easily be one the most entertaining and intriguing aspects of the game.
