They can&#x27;t. In order:<p>Eve is a murder&#x2F;capitalism simulator and has almost no physics in the first place. (There&#x27;s 3-dimensional positioning, but you can fly through planets and shoot through other ships as much as you like; also the entire world is static.)<p>No Man&#x27;s Sky is 90% an art piece with some added murder simulation.<p>Elite: Dangerous, also a murder&#x2F;capitalism simulator, only unlike Eve it&#x27;s more about the immediate visceral.<p>Notably all three of those pretend space ships are, like WW2 planes, subject to air drag, have a terminal velocity and have no automation on-board whatsoever, and astronomic physics aren&#x27;t even considered in the first place. These games are literally WW2 fan fics in &quot;space&quot;. (Or really, ether, as old-timey people thought of what&#x27;s between planets.)<p>If you&#x27;re looking to teach physics and astronomics, Kerbal Space Project does that quite well, even though it also ignores relativity and speed of light considerations.<p>More importantly, none of these games are even remotely able to tackle the topic of civiliations and saving them, which won&#x27;t be done with a gun, but with the word. The closest thing i can think of to that are the Mercenary games: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Mercenary_(video_game)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Mercenary_(video_game)</a><p>Edit: Not saying that the three mentioned are bad games, just that they can&#x27;t be taken seriously as space games.
