Okay, well maybe not Adventure! per se, but I was a huge fan of the adventure style games that were a staple of the video game industry through the 80's and into the 90's ranging from pretty much every Infocom game ever to the last real one I played which was Grim Fandango. What the hell happened to this genre (I cant really count Myst and the like here as they lack the story driven interface) and what are some of your all time favorites?
Mine are:
Quest for Glory I: So you want to be a hero?
Grim Fandango
Hitchhiker's Guide to the Galaxy
SF
