Cons
Con Not moddable
Con No tutorials, forums are "strange."
Con Not an actual engine
Con Lack of documentation
Con Not many developers use it
Armory3d seems to be quite exotic and it should be hard to find developers to help in projects.
Con Still in development
Con Slow development
Focus from the developer has shifted to another project, so development of this has slowed considerably.
Con Good looking but a terrible choice for any serious development
Terrible lack of support and lack of a serious delivery strategy. Multiple breaking changes to the master branches (usually the only branch actually) from the core projects as well as the myriad of dependencies it uses make it a nightmare to have something stable to create with. Might be good for prototyping if you stick to the releases, but stay away if you are planning to create something serious.
