head to head
Grand Theft Auto V asks more than Ghostwire: Tokyo, and the gap is reads.

Execution · Practiced Mastery
A first-person supernatural adventure cleansing a spirit-emptied Tokyo with elemental hand magic.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Ghostwire: Tokyo leans Execution (Practiced Mastery); Grand Theft Auto V 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.
Ghostwire: Tokyo
Aimed ether weaving and core-grab timing
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans clearly harder on reads.
Ghostwire: Tokyo
Spirits attack on fixed scripts
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostwire: Tokyo
Light enemy spawn variation
Grand Theft Auto V
Some mission and lobby randomness.
Ghostwire: Tokyo leans a little harder on optimization, though the gap is small.
Ghostwire: Tokyo
Skill upgrades and ability usage are easily systematised
Grand Theft Auto V
Heists, money loops, builds 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.
