Muffy was designed for a space opera campaign, where the players travelled around the galaxy in a high-tech spaceship we found (thank you, Weirdness Magnet) when escaping from Federation prison, fighting against the evil and oppresive regimes that dominated human space. Yes, all of us liked Blake's 7, which we watched quite a bit of just before the campaign began. When I designed her, I was aiming for a young, upbeat character with useful non-combat skills (medical and computing, to complement the pilot and the marine). We all had to be from groups that were discriminated against: I picked "women", the pilot's player picked "non-Caucasian", the marine picked "wouldn't kill civilians" and packaged it up with "killed superior officer". From this simple beginnings, I selected a picture (this was about two years after I started using pictures of real people for characters) and starting making her more complicated.
For a woman to have medical skills, she must have been exceptionally bright (to outperform all those boys with average scores on the entry tests) and have access to enough money to afford things like proper IT and course fees. She could have been from a rich family, but I didn't want to play Veronica Lodge with a social conscience. Most people live in massive urban ghettos? What's the most obvious way for a teenager from the ghetto to make significant amounts of money? Let's see if you reached the same conclusion I did. This was one of the few GURPS campaigns I've played in, and it helped reinforce my dislike for the game system. Give me Champions any day.
