Yeah, when I saw that I kinda agree with it. I agree with the first half of it at least. Gaming has gotten too much about releasing casual games to a group of people who view it in the same light as movies and bowling, easy, fun entertainment. People who play easy games, like Guitar Hero and Wii, aren't gamers. They've played a video game. Big difference.
On the other hand, I don't have much of a problem with games that are being made "accessible" to a wider range. Games like Fallout 3, Oblivion, and to an extent Bioshock, that have taken complex games and simplified them to allow a greater range of players are fine by me. They're still difficult/intense enough to keep away nongamers, while allowing starting and gamers who didn't play the earlier gamer, like myself, to enjoy them.
And then there are the easy accessible game, like Halo and, well most FPS games, that allow almost anyone to play and do ok, but are still not too easy. For me, these are the worst.
