This game, like the 5 book trilogy are absolute classics! A 20th and later 30th anniversary edition were put online by BBC and it's great. But honestly I'd still pay to have this game in the GOG style. DRM Free with the manuals and such. And I would love to have the text only original to play once in a while. I still sometimes fire up the classic Zork series. These Infocom games are priceless and Hitchhiker's Guide to the Galaxy has got to be the most frustrating of the bunch!
