Hello, the tutorials you link are still valid. awe6 is a semi-mature framework (5+ years) and tends not to change too much as a result, so anything you find is likely still relevant :)
As for more tutorials, we understand the request however awe6's design is intentionally abstract to allow it to be used with many platforms and workflows - so often a tutorial needs a concrete scenario. What would you like to do specifically?
Regarding the project developing; recent efforts were focused on mobile web (HTML5) with great results. There are many options for View: Dom, OpenFL, CreateJS. The latter is my preference and the supplied awe6 CreateJS driver includes many workflow helpers that extend the excellent core CreateJS library (e.g. asset manifests, macro preloader, automatic muting & pausing, fullscreen resizing, gui abstraction for easier porting etc). It can be used with Canvas or WebGL for browser across mobile and desktop and can be (optionally) wrapped by CocoonJS for mobile app publishing - making it a very diverse and powerful driver with a minimum installation / dependency base. For anyone entering the space today, I would recommend using the supplied CreateJS template as the launch point.
I am unsure who else is actively developing using awe6, but at my studio we use it to build dozens of promotional games each year for familiar consumer brands, and a few indie games on the side.
