head to head
Grand Theft Auto V asks more than Marvel's Spider-Man, and the gap is reads.

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

Execution · Practiced Mastery
Open-world superhero game whose joy is fluid web-swinging and rhythmic combat.
Grand Theft Auto V leans Execution (Practiced Mastery); Marvel's Spider-Man 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.
Marvel's Spider-Man
swinging flow and combat dodge timing
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Marvel's Spider-Man
thugs and bosses follow fixed patterns
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Marvel's Spider-Man
open world is fully discoverable
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.
Marvel's Spider-Man
gadget loadouts and suit mods are shallow but present
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.
