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

Optimization · Pure Optimization
A perk-driven sci-fi RPG won by flaw selection and dialogue routing.

Optimization · Pure Optimization
CD Projekt's first RPG, a dark fantasy of monster contracts and morally gray choices.
The Outer Worlds leans Optimization (Pure Optimization); The Witcher 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.
The Outer Worlds
FPS-lite with time-dilation aim
The Witcher
Rhythm-click combat needs only loose timing
The Outer Worlds leans a little harder on reads, though the gap is small.
The Outer Worlds
Scripted enemies
The Witcher
Enemies follow fixed styles and weaknesses
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Outer Worlds
Loot rolls, dialogue check variance
The Witcher
Some unknown quest outcomes on first play
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Outer Worlds
Perks, flaws, dialogue routing rewarded
The Witcher
Signs, potions, and style matchups form the real game
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.
