Then try out Basic fantasy.
"is a rules-light game system modeled on the classic RPG rules of the early 1980's. Though based loosely on the d20 SRD v3.5, Basic Fantasy RPG has been written largely from scratch to replicate the look, feel, and mechanics of the early RPG game systems. It is suitable for those who are fans of "old-school" game mechanics. Basic Fantasy RPG is simple enough for children in perhaps second or third grade to play, yet still has enough depth for adults as well. "
