The first video game I ever played in my life was Zork. The game was “written in 1977-1979 using the MDL programming language on a DEC PDP-10 computer.” (http://enwikipedia.org/wiki/Zork)
Yeah, ok. Too much techy talk. All I know is that we had an Apple II computer with a little black box screen and big floppy disks. The game was on loan from our uncle who was into computers and engineering at the university. We gathered around the screen and marveled at this fun text-based adventure. There were no pictures at all. None. There was only texts and prompts and you had to input short commands. You relied on your vivid imagination to play out the world of Zork, the Great Underground Empire, in your mind.
Zork was so successful that the MIT students that wrote it (Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling) went on to program another 2 games:
The Wizard of Frobozz
The Dungeon Master
Three of the programmers of Zork created Infocom in 1979 that was later taken over by Activision in 1986. Activision is a major player in gaming, based out of Santa Monica, California and noted most for creating The Call of Duty series.
So try Zork sometime if you’re looking for an old school adventure but mark my words, watch out for the Grue!
