I agree with the article, but I have some differing opinions also. I think that what we are seeing here is not new. This polarization has been happening for years, it just became plainly apparent now.
In the Golden Era of video games (which were the 90's as far as I'm concerned), game developers were born from bedroom programmers, tech geeks and role playing nerds. Development studios (with a maximum of 10-20 people) were formed around the common goal, a dream, to create something that the developers wanted to play, what they envisioned to be great fun, games that had meaning, and to show them to everyone, who wants to play it. There was no "Game Industry" back then, no business suits sitting in the CEO chair, no board of directors, no full-blown marketing campaigns or profit maximizing schemes... just geeks who made games and geeks who played them. A miracle of creativity, a new outlet for artists, writers, designers, programmers and nobodies with great ideas. The huge majority of them didn't wanted to get rich by making games, they wanted to create and make their dreams available to everyone to enjoy. But sadly some business people got wind of a new, emerging "industry" and so...
...the tables have turned (on us). Nowdays, games are made by programming "droids" based on focus groups, marketing research, business plans and profit projections, not by simple people with ideas. The term "good game" became the "game that sells". In this world, where the so called Game Industry is ruled by publishers and marketing agencies, the idea of "dreams" and "meaning" is lost in transaction. Well, of course they are playing it safe, because the publisher won't allow anything even remotely revolutionary because "what if it won't appeal to the masses". The reason is simple: lost profits. No, Portal wasn't daring at all, remember, they bundled the game into the Orange Box, along with Half Life 2, Ep 1 and Team Fortress 2. They haven't even mentioned the game in most marketing campaigns, or only just as a side note "oh, and there is this Portal thing in there also." They knew people would buy it for HL2, Ep1 or TF2, and if Portal would've been a failure, no lost profits there, but if it hits big, all the better, so they were safe either way.
But there is another side to this issue: Public Idiocy. "Never underestimate the power of stupid people in large groups" they say. With the birth of Gaming Media came public awareness. And what does the public do best? That's right, ***** about everything!! Enter the tabloid journalism, self-proclaimed experts, con-men, hordes of concerned parents/lawyers/activists...etc, and of course the dear "public opinion" itself. Games started to matter. Back in the day, games were largely ignored, people playing them were regarded as geeks with no life and when kids played video games, the parents were unconcerned, even if they took a closer look they thought "well, the kid is shooting at pixelated soldiers with pixelated guns, so what, its a game". But they forgot that in an instant when the mass media entered the scene. Everybody remembers the "VIDEO GAME KILLS AGAIN!" scandal(s) not so long ago, for example. Sensationalism came, and f***ed everything up. Now the public has been led into thinking that they "care" about video games by nitpicking every single detail that is not politically correct, tagging games as foolish, offensive or even harmful, making way for rating systems, retarded standards (green blood anyone?) various civil groups consisting of overprotective parents, self-righteous lawyers and zealous idiots who try to police video games. All the games got separated into categories once again, the M and the dreaded R-rating entered the scene, taking every game straight to Hell that had a drop of blood, a single scene of violence, a visible breast or genital, harsh words and everything that makes a topic even remotely worth mentioning and make it unrepresentable in a video game.
So now game designers are constrained by three huge brick walls. From one side, they have to work around these arbitrary limitations set by oversensitive retards (or face the music in the mass media: public ridicule, witch-hunting and lynching), on the other side, they are strangled by publishers and "higher-ups" to cater to every single living being on Earth, to maximize profits. And on the third side, there are the players themselves. A sea of self-righteous idiots hiding behind the anonymity of the internet, constantly bitching and bickering about every single detail that doesn't suit their special snowflake tastes. And game designers can't ignore them because of walls A and B. They can't ignore wall A, because they won't be allowed to publish games or they get dragged through the mud by the media. They can't ignore wall B, because they simply won't be able to get their game out there. It's an impossible situation, so no wonder they can't make good games anymore...
