I dunno if it's really about gaming anymore. It's about our core shifting from people willing to work at things to people demanding to be spoonfed things.
What are the games we enjoy the most? Minecraft, HALO, Half-Life... Are any of them "easy"? Nope
Is Peggle "easy"? Well...it's simple, but it's not easy.
But some of the more recent games? Try failing on them. Try really hard not to win, while still learning.
It's really tough not to win. Even on Street Fighter IV, with my first character, I leapt through the first eight characters with a simple series of commands.
Then up pops Seth. SLAM SLAM SLAM. Dead.
Ok...new tactic. SLAM SLAM SLAM. Dead.
Ok, redo the tutorial. SLAM SLAM SLAM. Dead.
So, most of this game it walks me through, and then to artificially inflate it, it sets me up against a baddie that can only be beaten by grinding skills?
Isn't that just like Civilization, Diablo, World of Warcraft, Modern Warfare, Bioshock and all the other recent games?
I think that's where the accusation of dumbing down comes from. Triple A titles have used Gamification to realise that you have to make the start of the game stupid and then stick an insurmountable wall in the way to lengthen playtime. Whether that wall is 1337 multiplayers, level relative bosses or simply collecting rings.
And this whole thing started very early on. But on those games were we climbed the insurmountable wall, we love them - because we spent time on it, beating them.
So we've been the ones asking for the dumbing down, but who "we" are has been changing since the hobby went mainstream. And it's only because it's mainstream that we have all the games to choose from.
But I will agree with Shamus, no blaming each other over it. This is a far more prevalent attitude than just gaming.
