I finally have a beef with Yahtzee.
I'm much too pessimistic to say that we are constantly making forward progress in game design. Adventure games, space flight simulators did not die out because they are archaic game designs, they died out because the market is demanding homogeneous games that everyone can enjoy. Unfortunately, that means games are heading down a path of less variety and creativity. Games will be something that everyone likes, but no one loves. That's why games like Braid need to be embraced. They are specifically not made for everyone. Games that might offend somebody are a very good thing.
Unfortunately, there are two contrasting types of games. The kind that challenges the player, and the kind that merely entertains/relaxes. If you try to do both, you almost always fall flat on your face. As we get older, we have plenty of real life challenges to deal with on a day to day basis, and the job of a video game becomes more about a stress reliever. But when you are a kid and have no real challenges, a game like Braid or Bionic Commando can offer one. As the average age of gamers increases, the less of a challenge the perfect, homogeneous game can pose.
Yahtzee should just realize that he is in a place in his life where he doesn't appreciate extraneous challenges in his life. That doesn't mean today's 12 year old doesn't. I think a lot of people deep down realize that they have lost the ability to rise to the challenge that a lot of old games offered, and they judge those games all the more harshly for it.
