head to head
Grand Theft Auto V asks more than Spider-Man: Shattered Dimensions, and the gap is reads.

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

Execution · Practiced Mastery
A scripted action romp testing combat timing and memorised boss patterns.
Grand Theft Auto V leans Execution (Practiced Mastery); Spider-Man: Shattered Dimensions leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Spider-Man: Shattered Dimensions
Combo timing and traversal demand moderate hands
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Spider-Man: Shattered Dimensions
Bosses and enemies are fully scripted, never 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.
Spider-Man: Shattered Dimensions
Linear levels with almost nothing hidden or random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Heists, money loops, builds learnable.
Spider-Man: Shattered Dimensions
Upgrade choices and learning boss patterns carry the rest
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.
