It was on a PS3.

I don't think Chris is so much trying to say that of all existing mediums, music is most like games, but is looking at its similarities and contrasts in order to pick out the most interesting aspects of games. When you compare games to music you suddenly start valuing stuff like, as you say, Jason, repetition, a point that you ignore or, worse, devalue when you compare games to film.

As such, it's absolutely valuable to compare games to existing mediums - not to get them to conform to them or to try to prove their significance - but to understand what games are by identifying their unique points and their similarities. Along the way, games can benefit from the tens, hundreds or thousands of years of learning that other media are built on.

Me, I think it's useful to compare games to architecture - they're places you visit that are designed for particular purposes; they tell stories and how you use them through their forms. And so on.

Games aren't music, of course, and nor are they architecture, but I kinda think I know more about games as a result of looking at them through an architecture or music prism.

So, isn't 'to entertain' a function which games require designing to fulfil?

That's really interesting, Winterblood. I hadn't heard of that issue before. I wonder what possible fixes there could be - might it have to come down to requiring a system to analyse where you're looking to dynamically fix that convergence point?

Another issue, which Andrew Oliver talked about when he presented to us Invincible Tiger: The Legend of Han Tao, the 3D game you saw at Develop, Emerald, was about objects which clip off the screen. In games with such free-ranging views as firstperson and thirdperson, you'll as a matter of course have objects displaying at the very edges of the screen. Rendering such scenes in 3D means that you'll often have one eye seeing an object but the other not, because the two images are slightly displaced to take account of the positions of your eyes. This leads to your brain getting confused. That why he chose to make a platformer - they could control the composition of the screen at all times to ensure that such clipping wouldn't happen.

It's a 360 exclusive - but yes, we'll try to run more of the basic info on games in future.
