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
A free-form fantasy RPG where skill-leveling and spell-craft builds dominate.

Optimization · Practiced Mastery
A narrative action RPG where build planning matters more than reflex execution.
The Elder Scrolls IV: Oblivion leans Optimization (Pure Optimization); The Witcher 3: Wild Hunt leans Optimization (Practiced Mastery).
The Witcher 3: Wild Hunt leans a little harder on execution, though the gap is small.
The Elder Scrolls IV: Oblivion
Real-time swing and block, modest demand
The Witcher 3: Wild Hunt
Combat timing matters but generous dodges forgive sloppy play.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Elder Scrolls IV: Oblivion
Scripted enemies
The Witcher 3: Wild Hunt
Enemies use fixed AI behaviours; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Elder Scrolls IV: Oblivion
Loot and level-scaling rolls
The Witcher 3: Wild Hunt
Loot rolls and minor combat variance only.
The Elder Scrolls IV: Oblivion leans a little harder on optimization, though the gap is small.
The Elder Scrolls IV: Oblivion
Skill leveling, spell crafting, exploit-prone builds
The Witcher 3: Wild Hunt
Builds, alchemy, and quest routing reward planning.
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.
