I’ve a few Supers ideas on the backburner. The main stay is however the cocnept of a UK-based Supers campaign set in the 1970s. Less four colour and more beige nylon and vimto. The same game would feature the darker side of the 70s – racisim, heroin, terrorisim, strike violence and chauvanisim. These ideas informed an abortive comics project the Scarlet Buccanner. If you want to know more of my (and associates) Superhero ideas find them here:
