I’ve brought this up before and I agree that it’d be very cool to see. Outside of the Unreal Engine Youtube channel/website and a couple of other Youtubers (Reuben Ward comes to mind) there isn’t a whole lot out there for beginner stuff, especially on the coding side of things which even if you know how to use C++ you need to learn UE4’s quirks.
However as cool as it would be to see courses for stuff like coding I’m not sure how well it’d mesh with the rest of the site seeing as CG Cookie primarily deals in the more artistic side of things whereas coding is a lot more technical.
At the end of the day UE4 stuff would – as an aspiring game dev myself – be amazing to see but even if it’s not implemented there’s still plenty of cool stuff here, and some of the Unity stuff is somewhat transferable to other engines too.
