G is a solitaire RPG about space and loneliness. The game is played over fifty-two turns. Each turn presents a random event determined by flipping a card from a stripped pack. The player then responds to the event by "creating something". Characters have three Gauges (Traits): Sanity, Health, and Happiness. All Gauges start at 10 and decrease from there, depending on events.
Create Something is a term used for a game process of creating a video, writing a journal entry, writing a dream journal, or creating an audio log. These fifty-two "somethings" are archived and preserve the record of play.
