 In terms of a more fine-grained system of statistics, a single "trait" would often be represented by a group of skills, one or more advantages and attributes, or a combination thereof.The first major role-playing game to use traits was "Over the Edge".Some systems, such as "Castle Falkenstein" and "HeroQuest", use traits as the only type of statistic, although they may use some other term for them, such as abilities.
