From the introduction: This is a solitaire game, played with very minimal components while attempting to capture the essence of a large-scale science fiction universe. It does this by using a system where you create elements as needed. Since a lot of “the blanks” will be filled in by you as you play, each game will be as different, and as creative, as you allow. ESNA Space! is a re-themed version of Epic Solitaire Notepad Adventures!! - Nameless Wanderer Edition, itself a revised and expanded version of Epic Solitaire Notepad Adventures!!.
