Since you mention game development - the architectures behind Love (https://www.youtube.com/watch?v=DPIA2g8T6Hw) and Bitsquid (http://bitsquid.blogspot.com/2010/04/our-tool-architecture.h...) were both big influences, demonstrating that it's possible to build composable tools while still having the accessibility of rich GUI apps.

Yeah games are a fun example to work with for such tools. Almost as if game development tools are an 'instance' of the prototype of 'development tools,' and rather than simply working on the abstract class it's nice to work on a prototype then expand. :)

Games also have an aesthetically-minded end point, rather than a solution-minded one, which keeps the focus on aesthetics/human values in focus.
