Clearly remember the concept behind Lena (first character) was Y.T. from Snow Crash. Fun fact: my intro to SD was done in concert with my boyfriend at the time. Within our first week in-city we definitely attempted to pickpocket Judge Murphy, which failed awesomely. And the boyfriend also later vindictively logged in as my character and flamed the staff and get me @newted, which I share because GUARD YOUR LOGINS!
Concept for Geronimo (second character) was high school history class, and he spent 90% of his time busking outside of the Drome (singing and getting drunk pretty much).
Concept for Navarre (third character)
Name: a nod to http://deusex.wikia.com/wiki/Anna_Navarre
Appearance: I was doing art projects for high school that required research into Indian art, henna, etc.
Fun fact: designed to be a short-term character to fill 8 weeks of vacation and then die of ...I had designed her condition with the aim of getting doctor characters more work to do (since this was pre-cyberware).
Concept for Goodman: I've always felt that the game is a great way to bring attention to important debates about the present day (ethics, identity, technology, religion) and wanted to challenge myself to see how intellectual concepts could be played out in a public way IC.
