A tabletop role-playing game (typically abbreviated as TTRPG or TRPG), also known as a pen-and-paper role-playing game, is a classification for a role-playing game (RPG) in which the participants describe their characters' actions through speech, and sometimes movements. Participants determine the actions of their characters based on their characterization, and the actions succeed or fail according to a set formal system of rules and guidelines, usually containing Dice-Rolling. Within the rules, players have the freedom to improvise; their choices shape the direction and outcome of the game. Read more on Wikipedia
