Hi @Bee
Creating Urban Games to invent and push the transformation to the circular city is right up my alley 
How can people help you? Do you have a collaborative document somewhere? If you have none yet, feel free to set up one and share the link here. You can use the forum for the document (It has a wiki functionality). If you want to start with a brainstorming we could have one in a video hangouts during the Open Labs for example?
But before I add more ideas - what is already there?
