7 Things To Know About HTML5

January 10, 2012 Article Start Previous Page 3 of 3

5. Browser Compatibility Isn't Uniform

If your players are running more recent browsers such as Chrome or Firefox, they should be able to play your HTML5 games just fine. But what about those still using older browsers like Internet Explorer 6, or previous versions of Safari or Opera? If users aren't updating their browsers, they won't have access to all of your HTML5 content.

At times, these browser compatibility issues work against one of the platform's greatest strengths: its ubiquity. If users are still using older browsers, they're excluded from playing HTML5 games.

Some developers, like Zynga's Bakaus, believe the best way to overcome this problem is to simply push forward with development, even when limited to newer browsers. By creating quality games that don't work with older software, users will be incentivized to upgrade, he argues.

"People are scared to abandon users at less than Internet Explorer 9," he said. "But sometimes, giving people what they want isn't helpful, since nothing will change. Try to come up with great new stuff that only works in modern browsers, and that will create incentive to upgrade," he said.

But if all users are running HTML5-enabled browsers, does this mean web apps will run equally well across all of them? Not necessarily.

Even when you look at browsers that support HTML5, that support is not uniform; older HTML5-enabled browsers might support only a limited number of features or APIs, meaning certain game features are only available to those who keep up with the latest browser releases.

And of course, if you're working with a limited budget, you might now have the resources to make a game that works across all browsers. At the New Game Conference in San Francisco, Bocoup's Darius Kazemi recalled that he encountered that very problem when porting Subatomic Studios' Fieldrunners to HTML5.

Kazemi explained that due to time and budget restrictions, he and his team chose to develop the game specifically for Google Chrome and the Chrome Web Store.

"Here's the dilemma," Kazemi said, "Do I reach the widest audience possible, or do I create the highest quality game? Can I have both?"

"In the end, do we get it on other browsers, or do we just create that quality experience on one browser? We ended up doing [the latter]."

Kazemi added that the game benefitted from some of the APIs that shipped with Chrome 14, but in the end the game was bound to a single browser. If you're going for platform ubiquity with your HTML5 games, be careful to plan your resources accordingly.

6. There's No "App Store"

One of the key ways in which HTML5 apps differ from native apps on mobile devices is that they lack a centralized app store to keep everything in line. This comes with its own set of pros and cons, but it's certainly worth noting before diving into the platform.

Of course, the main benefit of working on the web is that there's no approval process to submit, launch, or update your game. Unlike closed platforms like Apple's iTunes Marketplace, HTML5 allows you to update or launch your game whenever you like, with no need to wait through the bureaucracy of a platform holder.

While this freedom might seem appealing to up-and-coming developers, it comes with at a cost. Without a standardized distribution platform, getting your app in front of players becomes much more of a challenge.

"Right now, we do not have a major HTML5 'app store' to aid in discovery," said Putney.

Without a single destination for HTML5 apps, it becomes much more difficult for players to even learn about a new release. Putney said, however, that Facebook could certainly help in this regard.

"With Facebook enabling the social discovery of HTML5 apps on their mobile platform, it is a huge step forward," he said.

Google, on the other hand, views the open nature of HTML5 as one of its greatest strengths. The company's Seth Ladd explained, "I might say that it's actually easier to publish and distribute, because there's no governing body there, there's no up-front approval process. Everyone gets the freedom to monetize the way they want, log in to users the way they want, and publish they way they want. This is one of the strengths of the 'open' part of the open web platform."

7. It's Still Evolving

With all of HTML5's advantages and shortcomings, you'll have to decide for yourself whether it's right for you. Currently, there's no final specification for HTML5, but web developers are constantly adding to the platform, so who knows what things will look like in the coming years.

Google's Seth Ladd has high hopes for the future of HTML5, and notes that with such rapid iteration coming from the various working groups on the web, the platform is evolving faster than ever.

"I think what you're seeing now with Chrome, and Firefox, and even Internet Explorer to an extent, is that the specifications that come out of the different working groups in the spec bodies are moving at a much faster rate than they've ever moved before," he said.

With so many parties actively working on the platform, some HTML5 developers say it will only become more robust as time goes on. HTML5 developer Dominic Szablewski added, "This is HTML5's greatest strength. There's competition. After years and years of IE6 and Flash there's finally some progress with web technologies again and it's only just beginning. There's so much going on right now: WebGL, fullscreen mode, mouse lock, new audio APIs. It's truly exciting."

Companies like Zynga admit that HTML5 still has a long way to go until it can really compete with native app development, but if the platform can maintain its growth, the playing field could eventually even out.

Zynga's Bakaus said, "We're still early and that native apps have focused on game development for a long time already, so they've just had a ramp-up that we haven't yet."

Despite the optimism from existing HTML5 developers, the platform is still a challenge to work with given its ever-evolving state. Putney said, "We are essentially working on a car that is moving," noting that the changing specifications can introduce a number of technical hurdles in mid-development.

"But if we get things right, we can reach hundreds of millions of users with a successful app -- so we believe it is worth it," he said.
