Dude, you wrote One of the Living? Nice! That, and All Flesh Must Be Eaten in general, are great resources for zombie stuff. But I appreciate that book especially for looking at how to make AFMBE more than just a series of one-shots in wacky settings.Right. Back when those were written, nobody (to my knowledge, please correct me if I'm wrong) had done any sort of long-term stories with zombies.
I was basing them on the Romeroverse movies, which showed a progression of the world, if not necessarily the same characters from film to film. But they were very much intentionally written to be: "Hey, this is a weird situation, let's make the best of it and DAMMIT ZOMBIES!"
If I'd written those scenarios today, I would probably have them be a little more nuanced, a little more focused on long-term goals (see my book for AFMBE "One of the Living" for examples). But when I was 20, and the only person I knew who loved zombie movies, I just had fun with them. "Zombies come; everybody dies."
