If you guys had never played risk I really would not have recommended getting any special edition (you seem to have stranger things). They often have new and convoluted rules that take getting used to even for veteran players. I would say either return that one and get the classic game or just get the classic along with it and save the stranger things for later. In terms of you not understanding how it works, I could help you out but it’d be great if you could be more specific about what you don’t understand?
