You put your finger on the problem with this. I am very uncomfortable assigning points to game skills. In the RP everyone should be a hero capable of almost anything technically. It just makes for better believability if the someone who is frequently in the role of Engineer or Science, messes with electronics stuff – out of those available in the fiction. But any one of our regular engineering officers should be able to do that. You shouldn’t need a lot of “points”. Points break the illusion 🙂
I don’t think I am actually that great an Artemis game engineer, but I talk a lot as an engineer. I try to see the TSN world through the lens of “The Engineer” and other people then react to that. Then I added the lens of “wealthy merchant family”, but I make no pretense to special contacts in the research, diplomatic, intelligence or arts community.
