Younger generations and retro gaming.
Ugh, this topic... hurts, man. Watching kids trying to play old stuff almost physically hurts. Both my nephews are unable to finish SMB1's 1-1 without dying at least 5-10 times. They aren't able to figure out by themselves you can run by pressing B. They aren't able to catch a single mushroom, or the star. They'd never discover by themselves you can go in the fourth pipe. And of course, 1-2 is an unbeatable wall that halts their progress. They aren't able to reach the end of the level but I'd bet they could put 100 hours into the game and they wouldn't discover the warp zone behind the ending pipe.
And that's just one game. Others are just as disastrous, if not more. Their progress in NES' Kirby's Adventure is pitiful, and that's one of, if not THE easiest NES platformer, though I'll admit some of the later bosses in that game used to kick my own ass when I was a kid. But world 1 was always a breeze. Not for them, it's a massacre. In a game with 6 hit points that gives you unlimited fly.
Onto the SNES, same experience. DKC1's first stage, not beatable without at least 2 Game Overs. Second stage (the raining one with the ropes)? Impossibly high wall, they can't reach the checkpoint barrel.
Etc etc. It's an experience as fascinating to watch as it is depressing and bizarre. They're just not wired with the skill to do it.
