> Zork was updated about a dozen separate times between 1980 and 1984, to add polish and/or to fix bugs. It's funny how my first passing thought was "pushed-to-clients", but no, they had to batch bug fixes, QA, regression test (probably manual play?), see if it all fit back on floppies, create a master image, mail to factory, update printed literature and box design with version numbers, have retail boxed product delivered to Babbages (or whatever), possibly with instructions for removal of old inventory. Hard to fathom just how much easier it is to iterate in this age.
