14 DAY TRIAL // There are plenty of supporters of the web and all the new technologies that make it possible, Google being possibly the biggest one. But, while there's plenty of talk, outside of the big companies few people are doing new things on the web or using technologies in new ways.
HTML5 gaming for example is still mostly an idea than a practical reality. There are plenty of HTML5 Canvas and even some WebGL games out there, but any serious developer still relies on Flash these days.
The criticism is that HTML5 gaming is still not mature enough and that browsers aren't capable of handling the load without a hitch.
But what developers are missing is what the web, as a platform, brings to the table. For one, games truly are cross-platform.
Sure, it's unlikely that you'll be able to write code that works exactly the same on a large desktop monitor and on an iPhone, but it's still easier than having to rewrite everything for the platform you target.
Another important advantage is the fact that the web is open, there are no barriers to entry. What's more, games can tap into what makes the web different, into the things that other platforms can't provide.
Finally, despite the common misconception, there are already plenty of tools to get started with HTML5 gaming, from simple Canvas or WebGL helper libraries to full-blown game engines and even game makers.
Mozilla has put together a very comprehensive guide on HTML5 gaming, one that focuses less on the technical aspects and more on the overview, going from the tools you can use to build your game to how you can make money from it on the web.
It's a great article even if you're mildly interested in HTML5 gaming or the web platform, if only because it's a one-stop shop for several types of resources.
