>and why did the genre die?
For me it was voice acting. When it was just words on a screen you could zoom around the map, find all the findables, absorb all the clues and then get to work figuring out the puzzles. And if a puzzle took you a long time, and the solution made you feel stupid for taking so long to get it, it was a good puzzle.
But then CDROM happened and in the rush to do *something* with this new medium, point & clicks decided that making us spend hours of our lives listening to acting workshop grade hams drawl their way through endless reams of dialog was a good thing. Frequently the solution to a "puzzle" was simply "keep talking to NPC until they run out of dialog and then a flag will be set that will let you continue." And this single "activity" is literally 15 minutes of your life. 15 minutes of terrible, god awful bullshit read slowly and carefully like it's a parent reading to a small child.
