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

Optimization · Pure Optimization
The deepest optimization puzzle in the Infinity Engine lineage, rewarding encyclopedic knowledge of 2nd Edition AD&D systems.

Optimization · Pure Optimization
A theorycraft-dense ARPG about engineering builds through randomised loot and crafting.
Baldur's Gate II: Shadows of Amn leans Optimization (Pure Optimization); Path of Exile leans Optimization (Pure Optimization).
Path of Exile leans a little harder on execution, though the gap is small.
Baldur's Gate II: Shadows of Amn
Pause-and-plan removes twitch entirely; micro-placement has marginal value
Path of Exile
Some dodge and reflex play, but build carries fights.
Baldur's Gate II: Shadows of Amn leans a little harder on reads, though the gap is small.
Baldur's Gate II: Shadows of Amn
Enemies run scripted behaviour patterns, never modelling your tactics
Path of Exile
Mobs and bosses are scripted; no adaptation.
Path of Exile leans a little harder on variance, though the gap is small.
Baldur's Gate II: Shadows of Amn
Loot randomization and enemy ability use create hidden-information layers
Path of Exile
Loot, map mods, and crafting outcomes are heavily random.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate II: Shadows of Amn
Mage spell sequences, dual-class builds and Spellhold routing define mastery
Path of Exile
Passive tree, crafting, and economy form near-infinite theorycraft.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
