In the past, games actually made you think. If you wanted to find your way you either had to explore, or look for clues when talking to NPCs and such. Puzzles were often clever and didn't give you many hints at all.
Today, all you have to do it lock your eyes on the minimap for waypoints, and if you can't find the solution for a puzzle in 1 minute, a prompt shows up that gives you the answer directly (Uncharted and The Last of Us are major sinners in this case).
Why is this? I mean, I know why. There are lots more people playing now, but WHY is this? Is the average gamer today dumber, or at least less patient, than us who grew up during the 80s and 90s? Is all they want instant gratification? Don't they want to earn the reward by themselves?
I don't care if I give off a "the old days were better, dumb kids!"-vibe, because my favourite hobby keeps require less and less brain power. Soon you can just look at the screen and just press forward, and the game will complete itself.
And yes yes, I know that there are still indie and AA games that are designed like in the 90s, but back then even the highest, most expensive games didn't just hold your hand and give you participation trophies for just putting in the disc.
