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

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
A precision metroidvania about learning fixed boss patterns and tight platforming.
Grand Theft Auto V leans Execution (Practiced Mastery); Hollow Knight leans Execution (Practiced Mastery).
Hollow Knight leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Hollow Knight
Precise platforming and pogo timing dominate hard content.
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Hollow Knight
Bosses run scripted attack pools; not adaptive.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Hollow Knight
Negligible; world layout is fixed.
Hollow Knight leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
