Adventurer Conqueror King System
A variant of D&D that draws from the Basic Set version - including combined race and class and strict 3d6 attribute rolls. Attacks¸ saves¸ and proficiencies are all recorded as the target number on 1d20¸ like ""14+"" (called ""throws""). Resolution is by rolling 1d20 + modifiers compared to the throw number. Advancement is level-based¸ but also divides into three categories (adventurer¸ conqueror¸ and king) where the characters progress into developing followers and territory. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.

Enter a world where empires totter on the brink of war¸ and terrible monsters tear at the fragile borderlands of men; where decaying cities teem with chaos and corruption¸ nubile maidens are sacrificed to chthonic cults and nobles live in decadent pleasure on the toil of slaves; where heroes¸ wizards¸ and rogues risk everything in pursuit of glory¸ fortune¸ and power. This is a world where adventurers can become conquerors - and conquerors can become kings.
