ABSTRACT
Our concern is now to give flesh to most of the eight models and structures already described and to embody them in a context. To see them dance, however, would need an experience of them in action. Many games play much better than they read, but at least a quick reading can indicate the scope and adaptability of the models. They are certainly not models of excellence but indicate work in progress and might perhaps spark an idea that will help enrich a particular group project in a particular situation. Everyone in this field works by adapting other people's ideas, there is little that is really new under the sun.
