I love Dr. Who. Here’s a solo game that lets you help the Doctor save the universe. From the game description:
‘Doctor Who’ is a paragraph based solitaire story game. You read various numbered sections one after another but the sequence of the paragraphs is determined by rules and tables. Each describes a new situation, or provides rules about the choices and actions you can make. There are plenty of events and situations, so each game will be a new, fresh experience.
