I personally feel this may be taking the "games as art" discussion a bit too far. Yes, some games are art, and almost all games have artistic value. But when I'm playing Quake, I don't care about any of that. All I care about is that it's fun and it's challenging and I'm playing with my friends. Just like when I'm watching the latest summer blockbuster, I don't care that it won't win an Oscar, or that the girl in the plot is really just there to stand around and look pretty, or that the hero is somehow surviving things that no human could withstand. It's fun.
I could go through Ico with this post and glean a lot from it. Taking the same thing to Battlefield 3 might yield substantially different results. I personally don't care. Not all the music I listen to is art, either.
