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 · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Optimization · Practiced Mastery
Open-world Hyrule built on physics puzzles and exploration over reflex tests.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
The Legend of Zelda: Breath of the Wild
Parry timing and aiming matter but forgiving.
The Legend of Zelda: Breath of the Wild leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
The Legend of Zelda: Breath of the Wild
Enemies follow fixed scripted behaviors.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
The Legend of Zelda: Breath of the Wild
Weapon drops and weather lightly randomized.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
The Legend of Zelda: Breath of the Wild
Shrines, cooking, traversal routes fully solvable.
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.
