Sorry it is not really related (except about the "easily share assets", but I ask myself if we could make a kind of communautary account on http://opengameart.org/ in a way to share all the assets, art, code, shaders, templates and prefabs we build of the community.
I am imagining a tool where we could (maybe in the launcher) import and export inside a big community bank of assets for superpowers, and help each other to build games collaborativly in this way. That would be nice, sorry I day dreaming.
