I'll go in a different direction and recommend either:
-Barbarians of Lemuria Legendary Edition, or
-Legends of Steel Barbarians of Lemuria Edition
Both use almost identical rules (the latter uses the rules of the former, but with a different setting). Pretty light on rules, you have attributes, "careers" (which are basically skill groups), and combat abilites. Resolution boils down to
-roll 2d6
-add whatever modifiers are appropriate based on attributes, careers, and combat abilities
-try to beat difficulty number (usually 9, can be modified for easier or harder tasks)
Resolution is very quick, and the game flows smoothly.
The setting of Barbarians of Lemuria is more sword and sorcery weird fantasy (unusual monsters, animals, and races). The setting of Legends of Steel is more traditional-it is still labelled sword and sorcery but could be run as high fantasy if desired (it is humans only, no other PC races).
