"For those game developers who do not have a development environment or prefer to use the Intel XDK to develop their game apps, the Intel XDK Game Asset Manager provides a central place to view game assets during game development. The Game Asset Manager supports certain game engines and versions that must be specified when you create the Intel XDK project. When you use a supported game engine (and its version), the Intel XDK can also generate code snippets for a selected asset that you can use to help develop your HTML5 game sources."
