> Really? Compared to film, music, visual arts? I would say it's the least diverse of them. It's starting to branch out, especially in the indie scene, but it's still in it's infancy.

Yes because gaming actually unify all other art medium without being burdened by their 'rules'. Movies today have clearly defined cinematographic rules, very little professional produced movies can be deemed experimental. Games do not suffer from these kind of 'academic' considerations.

I don’t think you have much knowledge of film if you say “professional produced movies are not experimental.”

This doesn't make sense. What are the rules of music? Sure if you want something on the radio it's wise to follow some guidelines, but obviously that's not where the diversity is. You can make a song with no defined key or time signature, it can be hours long or seconds long, it can have no vocals, only vocals, or controversially, no sound at all. You could go on and on. Video games have not pushed the limits in this way.

I have to strongly disagree with this.

What we call "video games" now encompasses pretty much all other art forms except cooking. Whatever you can do with one form, you can do the same thing plus more in a game. There is much greater artistic potential in this kind of software than anywhere else that doesn't require physical presence (and even that can be simulated). It also requires massive engineering skill, itself an art.

That being said, the medium has a very long way to go yet and there are still many areas it has yet to explore. I'm very glad there's a thriving indie scene where developers are continually experimenting with fresh, crazy new ideas.
