True20

A universal role-playing game derived from the d20 system, supporting fantasy, modern, science-fiction, and other settings. Players create characters using one of three roles—warrior, adept, or expert—and can choose skills freely regardless of role. Most actions use a single twenty-sided die and simple ability modifiers. Characters gain new feats at each level, with magic represented as feats rather than leveled spells. Damage is tracked through conditions instead of hit points, and characters advance when the Narrator determines that they have completed an adventure or series of adventures.
