CreateJS Modular Tool System
CreateJS is not similar to a lot of other HTML5 game engines. CreateJS is a package of modular tools and libraries that work together or independently for your project. These include EASELJS, which is a canvas library and SOUNDJS which as the name implies is for sound.
They are not alone because more libraries come included with CreateJS. They also boast and incredibly easy installation when compared to other libraries and function across all major browsers. CreateJS is also the leader in HTML5 based advertisements it claims on the site with the ability to create interactive ads with it. The library is actively updated and worth checking out here.
