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

Execution · Practiced Mastery
Open-world western about an outlaw forced to hunt down his old gang.

Optimization · Practiced Mastery
A demanding action RPG where dodge timing meets alchemy build planning.
Red Dead Redemption leans Execution (Practiced Mastery); The Witcher 2: Assassins of Kings leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Dead Eye softens but gunplay still wants aim
The Witcher 2: Assassins of Kings
Tight dodge and parry windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Multiplayer skirmishes add light human prediction
The Witcher 2: Assassins of Kings
Scripted enemy patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption
Ambient events and spawns vary mildly
The Witcher 2: Assassins of Kings
Some loot and alchemy variance
The Witcher 2: Assassins of Kings leans a little harder on optimization, though the gap is small.
Red Dead Redemption
Mission approaches and economy are learnable
The Witcher 2: Assassins of Kings
Sign, alchemy, and skill builds matter
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.
