I used to play Arkanoid back in the day. I never saw the ending. That's because they didn't have YT back then. They had books with tips on how to play better. People would hang out in Barnes and Noble reading them. Then the internet came along and eventually YT where people could learn how to win.
Yesterday I was playing Donkey Kong 64 on the Steamdeck going through the beginning. I was playing along with a walk through which goes for 10 hours and the person gets every coin, every banana, doesn't lose a life, takes no damage, incredible. He recorded this on a PC running the Mupen64 emulator.

Back then I would play a game for a while then get stuck and move on. It would probably take me 40 hours to go through DK64 with a walk through. I have to watch the video, get through that part, then come back and see what's next.
When you think about it, a game is nothing more than figuring out a challenge. Either pushing buttons or making movements in a certain way, or doing it faster and better than someone else. Most games have walk thrus or speed runs today. That's how I'm playing Doom Eternal on the PC, with a walk through and it's still hard even on easy. That's because the zombies come in waves all at once, and I run out of ammo and there's so many weapon combos to remember to kill each one.
