The Great Infocom Replay: Zork Ⅰ
Zork Ⅰ is a really important game to work through, if you’re going to try to understand where interactive fiction came from. It’s not the first, but it’s a major early milestone of the golden age of commercial IF, and its book is alluded to repeatedly throughout later works. I’m really glad that I’ve played Zork Ⅰ, but my feeling after playing it again is that once was probably enough.
