I realised after submitting Sturm und Drang that it was based (subconsciously) on a game called The Life and Death of… by John Keyworth, designer of Intrepid. (Sorry, John: sincerest form of flattery and all that.) It started out being called ‘The Romantics’ but modernised itself according to Patti Smith’s precept that the secret of improvisation is rhythm. Not a consistent beat, necessarily, but rain and sun and a buffeting wind, like sex or a mountain walk. It’s pretty impenetrable. Sometimes when you reach out for something new you find something someone has already done.
