An attribute is a piece of data (a "statistic") that describes to what extent a fictional character in a role-playing game possesses a specific natural, in-born characteristic common to all characters in the game. That piece of data is usually an abstract number or, in some cases, a set of dice. Some games use different terms to refer to an attribute, such as statistic, (primary) characteristic or ability. A number of role-playing games like Fate do not use attributes at all.
