I frankly couldn't care less about modern video games, so I'm talking about the Nintendo 64 and earlier eras.
For example, I was recently trying out a bunch of Nintendo 64 games on my Everdrive 64, many of them ones which I have played in the past. But many of them wouldn't quickly start, but rather insisted on lengthy, unskippable cutscenes.
For example, Majora's Mask, Donkey Kong 64, etc.
Even when the games were new/current, it is more than possible that somebody could have watched the intro at a friend's house, then bought their own copy and wanted to start playing right away and not have to sit through unwanted story nonsense. Or maybe they simply wanted to re-play the game from a new save. Or they saw the intro already in a commercial, or from a demo unit in a store. Or they just don't care for story/cutscenes at all, even once!
Not to mention the "speedrunners" of today who have to constantly sit through many-minute long cutscenes constantly...
There is typically no way to skip these. You can press every button on the controller until they turn to dust and it won't let you skip the cutscenes.
What could possibly be the reason for doing this? Even if they were worried that somebody would skip them by accident, why not make at least one button, such as "Start", allow you to skip it? Even requiring multiple presses in a series would be wonderful, and clearly signals to the game that the player does not wish to see it but rather just get on with the actual game.
I do not understand why they would piss off the player like this for seemingly no reason, yet it was (and maybe remains) common. What could possibly have been the reasoning? Is it known? Have they spoken about it in interviews?
