From the introduction: ESNA is a solitaire game, played with very minimal components while attempting to capture the essence of a large-scale fantasy World. It does this by using a system where the player creates elements as needed (instead of providing a large tome of data, Creatures, weapons, etc, at the start of the game, like most other fantasy games). 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 yourself to be.
