True, but since you're responding to my post, I'll clarify that I do know what Zork is and my objection was to linking to a legendary name without any relevant context such as which version of Zork and no explanation of the Z-Machine interpreter. Especially when Infocom, ZIL, the Z-Machine and Zork have already been the subject of so much retro archaeology, commentary and even subsequent enhancement and expansion.
