I'm the author of Terminator. The in-game explanation for why the protagonist of Terminator barely mentions the rest of the crew (besides the captain) is that her job in this mission is to control the robots, and this is so absorbing and so time-consuming that she's entirely focused on it and can't pay any attention to the rest of the crew.
The real-world answer is that I didn't have time to implement the rest of the crew or really anything else about the spaceship you're in. Also I thought that they're pretty much irrelevant to the gameplay so I shouldn't direct the player's attention toward them.
