         | As for conlangs: many years ago, I worked on a game where one

         | I spent quite a bit of time trying to generate realistic
         | English and despared that it was just never very believable (I
         | was young, I didn't have a good understanding of what was and
         | wasn't possible).
         | 
         | At some point, I don't remember exactly why, I switched to
         | having the NPCs speak a fictional language. It became a puzzle
         | in the game to have to learn this language. But once you did
         | (and it wasn't hard, they couldn't say very many things), it
         | made the characters feel much more believable. Obviously, the
         | whole run-around was just an avoidance of the Uncanny Valley,
         | where the effort of translation distracted you from the fact
         | that it was all constructed. Though now I'm wondering if enough
         | exposure to the game and its language would eventually make you
         | very fluent in it and you would then start noticing it was a
