Gothic Worlds presents a setting which begins as a mundane, Medieval world much like our own history. Then a source of magic is introduced and humanity begins to tap into it to alter history and events. The game proposes only one race--humans. Characters select Classes which guide their development. The game provides these Classes: Archer, Barbarian, Black Mage, Blue Mage, Green Mage, Knight, Red Mage, and White Mage. Each color of Mage aligns with a "school" or sphere of magic. Characters also have Fortune Points which are gained and spent during play.
The game uses standard d6 but proposes a special use called d6% where 2d6 of differing colors re rolled and one is used for the tens position and one for the ones position, yielding a discontinuous 2-digit number from 11, 12, 13...to 64, 65, 66.
Combat is resolved by using a character's Combat Stat with a multiplier and trying to "roll under" this with d6%; the "to hit" roll also determines hit location if it is successful. The game includes a magic system keyed to Class, equipment lists, and a character sheet with hit locations.
