SIMS, but Make It Education
I was kind of fascinated by the idea that Geiger and Rickard came up - essentially a prompt-based class role-playing (???) game. I played some of those as a kid, along with various other role-playing games, and I'm sure that it was a formative experience for the way I write now. Mostly because it was a LOT of writing - I noted in my response paper to this chapter that often the minimum word count per post was a 1,000 words (role play moderators could be very strict about that!), and sometimes I would write three of them a day. I can't tell you the last time I wrote 3,000 words in a day. I'm not even certain that it really classifies as role-playing, since you yourself are the "character," but it's certainly similar to the way those work. My first thought while reading about the MOO was that it seemed kind of outdated - if I were to envision a similar kind of software now, I think it would be a more visual, with actual virtual "spaces" and avatars.
