I work on a team with a graphic designer who cannot code at all, and is doing amazing things with Unreal Engine. This includes coding shaders (yes, shaders!) using only the blueprint drag and drop system. You just set up how you want it to look, and the system compiles it to shaders under the covers. The technology is super amazing.

The revolution in competition for indie game development platforms is here. I don't know why Crytek is doing, but Unreal Engine is very usable and amazing technology.
