Castles & Crusades

Castles & Crusades (C&C) is a fantasy role-playing game published in 2004 by Troll Lord Games that is based on a simplified variant of the d20 System created by Wizards of the Coast. The game system is designed to emulate the play style of earlier editions of the Dungeons & Dragons game while keeping the unified mechanics of the d20 System. It has been credited with birthing the Old School Revival (OSR) in fantasy role-playing.
