The actual title: "Towards improved support for games, graphics, real-time, low latency, embedded systems."
These little pieces of censorship—that's not a sign that for some reason, we really don't like to talk about games. There's no pervasive second-class-citizenry attitude towards gaming. I don't really know how to interpret the omission, other than it's a little piece of little consequence.
Gaming keeps surfacing in places big and small as a motivation behind some technical or business innovation. Here we get very real improvements to the STL. This certainly matters: we celebrate Quake's square-root estimation trick as a cultural artifact, evidence of the beauty of programming. Elsewhere, in recent news, we hear Stewart Butterfield's narrative, which was as much about Flickr and Slack as it is about his twice-failed game concept. Lots of ideas and characters in the tech world have touched gaming in one way or another.
In my personal background at my startup, I keep running into folks pushed out of gaming. They start making "apps." Surrounded by app people, I might miss that a third of all new apps in the App Store are actually games[0]. Even then, games are disproportionately represented in Apple Design Awards. It's tough to get an accurate figure we'd all agree on, but I believe games are nonetheless also overrepresented in revenue (definitely from the looks of top grossing, if we're strictly speaking about mobile software).
If we really want to talk about software, I'd expect 1/3 to 1/2 of the content on the front page to actually be about games. It's certainly what most software people are working on, and it is probably where the plurality of the money is made. I'm not going to speculate as to why (I'd leave that for certain ex-Google developers, who possibly wanted to make a card game all his life). Here, we're actually seeing gaming omitted from the title, as though it's verboten.
