I thought some people here could appreciate this story on Kotaku:

Some of those maps aren't really homemade, but were included as feelies with the original text games, and are included as bonus material here on GOG. Still, nice to see something like Zork still gets recognition of some sort on Kotaku even today!

Thanks for posting. Was a good read.
