No harm in giving a nod to other sci-fi stories/franchises. Science fiction has been fertile ground for shaping the reality of the future, and we all owe a debt of gratitude to those whose vision led to many of the things we take for granted in real life today. Acknowledging some of those visions in the fabric of CF improves its appeal and relevance, but of course, in a modest way, so as not to dilute the concept and character of the game.
