Shades of Grey 
(1997 Mark Barker et. al.)


This is a unique game in that it is a collaboration of 
6 authors on Compuserve (a defunct online service) who 
never met each other in real life (well, maybe now they 
have). Amazingly, all the episodes in the story comes 
together seamlessly despite the fact that they are written 
by different authors. The cliche story at the beginning 
of the game (you have an amnesia) quickly turns into a 
fascinating page-turner about the consequences of one's 
actions. Highly recommended.
