I don't think it is stubbornness but rather how we as a society have evolved and also because we are now adults .
When you are young you are more impressionable as you are experiencing something for the first time and those memories burnt a lasting impression.
When you are an adult and you have your own disposable income, your way of thinking changes, and time becomes precious and by that stage have played many games if something doesn't impress you straight up like it did in the past as a child you dismiss it as there is so many more options out there now to get your gaming fix.
Personally I think the age of information all though it is a great resource, rather than just enjoying things in life (games, movies, collectables, sport or whatever it may be), we over analyse everything about it and try to pick faults with it. through arguments with others online. Did we do that as a kid? not so much as our minds were innocent and were just happy to have a new game to play. Social media/smartphones has shortened our attention spans also. so if you can't get a buzz from something in the first hour you probably will think the rest of he game is crap.
As most of us here are now adults and have our own disposable income, as the old saying goes money does not buy you happiness. Does it make life easier? sure, but when things become the norm (i.e. multiple new games purchased each week) vs when you were a kid maybe one every few months as you had to save up your pocket money to buy the game the special feeling that you got from it also isn't the same as you have more of it lol.
To end my post, this is what stubbornness is. When I was a young lad and the first time I installed itunes on my PC and it killed it for some reason with a blue screen of death that required me to reinstall windows, is the day I decided to never buy an apple product or install any of their software. Now I am sure it was just a bad coincidence of why it happened, but because it happened I am now too stubborn to even entertain the idea of giving an apple product a try ever again in my life lol.
