togelius writes "What makes games fun? Some (e.g. Raph Koster) claim that fun is learning — fun games are those which are easy to learn, but hard to master, with a long and smooth learning curve. I think we can create fun game rules automatically through measuring their learnability. In a recent experiment, we do this using evolutionary computation, and create some simple Pacman-like new games completely without human intervention! Perhaps this has a future in game design? The academic paper (PDF) is available as well."

Zonk points out an opinion piece at Gamers With Jobs about Braid, an independent platformer that received high praise when it was released a few months ago. It's often held up as an example of "games as art," and in this article, Julian Murdoch comments on the act of interpreting such art. He takes Braid's creator, Johnathan Blow, to task for the effect his comments have on the game and its players: "My frustration with Braid is multiplied because it would seem to have been designed with me specifically in mind. I am a student of the obscure. I am pathologically drawn to books, movies, games, and passages of scripture that are dense, difficult, and which hide (and thus reveal) meaning behind layers of art and artifice. Games lend themselves to this layering more than any other medium. The casual player of Oblivion, System Shock 2, Fallout 3 or Bioshock can have an extraordinarily story-light experience if they simply 'play' the games. One layer deeper, a close reading of the environments informs deeper levels of story. Deeper still, evidence in the form of written texts and audio tracks provides footnotes, side-plots and appendices to a central story. ... by the end of my Braid experience, I felt like Blow had specifically constructed something that would generate emails and forum posts begging him to please tell us 'what it all means.'" There is some interesting discussion in the comments, including a response from Blow himself.
