There are roleplaying systems that do embrace the complexity (and well beyond CPRG).
Here's an "attack table" for one specific weapon in Rolemaster: you roll a 1-100, add and subtract a whole lot of offensive and defensive bonuses and end up with a result like "15DK" -- 15 hit points of damage and a severity D critical hit on the K (Crushing) table. The broadsword can give both Crushing and Slashing criticals. That again has 20 random outcomes such as "Strike lower level; tear tendons. Foe is at -25%. +3 hits. Foe is stunned and unable to parry next round"
