From publisher blurb: Mix Texan individuality and Mexican community, with a dash of existential crises and threats to their way of life, and you get the dying oil town of Rio Libre. Los Días Últimos is a Backstory Cards Setting Grid to use during the Backstory Cards process. Taking turns going around the table, each player draws a Backstory Card and answers the prompt on the card, referring to the setting grid for random elements. Think of it like a dynamic campaign or one-shot outline.
