Would anyone be interested in doing one? For reference a Superbuild is usually when you pick out a large scale thing to build, most often a place (for instance all of Middle Earth, the entirety of a Zelda game world, etc.) and work together with a few project organizers to make it. The hardest part about getting started is agreeing on what to build (and for the sake of being original make sure it has not already been built). I have wanted to try such a project in the past, but have always found a lack of interest or impossible to agree on the project.
