Zork Zero, by Infocom In its death throes (Activision would shut down the studio the next year), vaunted text adventure game company Infocom shifted the much-beloved Zork series into the graphical realm with Zork Zero in 1988, designed by longtime Infocom IMP Steve Meretzky (Planetfall, Hitchhiker's Guide to the Galaxy, et al). A prequel to the previous Zork games, Zork Zero would introduce interactive mapping, a rudimentary GUI, in-game hints, interactive encyclopedia (the Encyclopedia Frobozzica) and mini-game to the series, along with... oh yeah, graphics! This was the last Zork game before Infocom was shuttered, and while none of us ever wanted to see Infocom's demise, I guess this is a pretty fine way to go out.
