I have been following Armory for a while (almost since its inception), but I am not a programmer, so interfacing with it has been a roadblock. I have used UE4 and its Blueprint system (node-based programming), and if you have not used UE4, I suggest you give it a try - if for no other reason than you can download AAA game assets, open them up in UE4, and dig into them to see how they do the things they do. This includes C++ files which allow for many more things than Blueprints alone.
