=Platform Games=


The platform games initiative is made up of a core team whose works is primarily focused on making the Gecko platform, Firefox Desktop, Firefox OS, and Firefox for Android the best it can possibly be at running games. The core team is ready to help coordinate with other groups in the community who are working on features or optimization that are important to game developers and provide assistance when needed. Platform development continues to focus on games and we hope you are as excited as we are to make HTML5 rock on the web!

=Mozilla Games Technology Roadmap=
==Games Platform High-Level Status==
There are two levels to this document. The first is the Roadmap section which contains areas that are currently in development and we have a reasonable level of confidence we can address in the next year. For the topics that are listed in the Under Consideration section, we are actively investigating the best way to address them.


==Roadmap==
Please visit this [https://wiki.mozilla.org/Platform/Games/StatusUpdate page] to view the high-level status of the web games program.
