This cut up solo supplement is system neutral, but focused on Space Opera as a genre.

Cut up solo is a method of solo roleplaying where texts, in this case the first two E. E. "Doc" Smith Lensman novels are chopped into four or five word 'snippets'. You then draw snippets at random and try and join them up to create sentences or paragraphs of what the GM in a roleplaying game would say to you. You can then roleplay against that, reacting to the text you built, and then the process repeats.

This supplement consists of a PDF book containing 2000 random snippets from the novels, and spreadsheets set up to randomly sample the texts that contain 35,000 snippets.
