head to head
Grand Theft Auto V asks more than Gravity Rush 2, and the gap is reads.

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

Execution · Practiced Mastery
Expanded gravity-bending sequel with swappable physics styles and a bigger sky.
Grand Theft Auto V leans Execution (Practiced Mastery); Gravity Rush 2 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.
Gravity Rush 2
Juggling three gravity styles mid-combat
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Gravity Rush 2
All foes 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.
Gravity Rush 2
Deterministic authored content
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.
Gravity Rush 2
Talisman crafting and style-matchup knowledge
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.
