When I was reading the story I confidently thought - I know how this goes, for sure Terminator was based on Second Variety. I was very surprised that Screamers was the movie licensed from the story because the Screamers part of the story is just the introduction/setup for the main plot, and the movie simply used the setup technology for the entire plot which kind of misses a point of the story in a way.
