The astonishing text adventure Amnesia by Thomas M. Disch (Electronic Arts, 1986) also did something like this. The copy appeared to let you play (with an obnoxious codewheel on top of a custom disk format), but you got stuck in a hotel room you can't leave. https://en.wikipedia.org/wiki/Amnesia_(video_game) https://en.wikipedia.org/wiki/Amnesia_(video_game) and an amazing writeup giving some background of Disch and the game is at www.filfre.net/2014/09/amnesia/ For the time, really an amazing game, if frustrating and flawed in places.
