I also think this signals a change in how games are played these days. There are many players that don't want to be challenged or explore, they want to complete tasks and get rewards. Some of them don't really care that much about the actual gameplay, as long as there is a quick way to complete sets of tasks and get their rewards. Some of my friends are like this, they blast through games without looking at anything…
Has that really changed recently? Different people have always enjoyed different things, and some don't like puzzles. That was as true a hundred years ago as now.
It becomes quite obvious when you play a game of the early 90s and compare it to gameplay of today.
If you couldn't identify(!) and solve the puzzle in a LucasArts Adventure Game, you were stuck, if you repeatedly died in Super Mario / Sonic the Hedgehog you had to restart from Level 1.
