head to head
Hollow Knight asks more than Grand Theft Auto: San Andreas, and the gap is execution.

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

Execution · Practiced Mastery
A precision metroidvania about learning fixed boss patterns and tight platforming.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Hollow Knight leans Execution (Practiced Mastery).
Hollow Knight leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Hollow Knight leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Hollow Knight
Bosses run scripted attack pools; not adaptive.
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Hollow Knight
Negligible; world layout is fixed.
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
Hollow Knight
Charm builds and boss routes are fully learnable.
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.
