Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A pausable tactics RPG where party build and tactic-slot planning win fights.

Optimization · Pure Optimization
An original RPG system where engagement optimization and passive-stacking theory dominate hard-mode encounters.
Dragon Age: Origins leans Optimization (Pure Optimization); Pillars of Eternity leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Origins
Tactical pause combat, low input demand
Pillars of Eternity
Real-time-with-pause removes all twitch pressure from the player
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Origins
Enemy AI is scripted
Pillars of Eternity
All AI opponents use fixed scripted behaviour trees
Pillars of Eternity leans a little harder on variance, though the gap is small.
Dragon Age: Origins
Hidden rolls and loot tables
Pillars of Eternity
Hidden enemy immunities and ability distributions require investigation
Pillars of Eternity leans a little harder on optimization, though the gap is small.
Dragon Age: Origins
Tactics slots, builds, party synergy dominate
Pillars of Eternity
Per-encounter ability management and passive stacking define trial-of-iron mastery
