head to head
Resident Evil 7: Biohazard asks more than Grand Theft Auto V, and the gap is optimization.

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

Optimization · Practiced Mastery
A first-person haunted-house survival game solved by crafting optimisation and scripted-enemy routing.
Grand Theft Auto V leans Execution (Practiced Mastery); Resident Evil 7: Biohazard leans Optimization (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.
Resident Evil 7: Biohazard
First-person aiming and blocking under Molded pressure matters
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.
Resident Evil 7: Biohazard
Family AI follows scripted stalker scripts, never adapts to you
Resident Evil 7: Biohazard leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Resident Evil 7: Biohazard
Limited item locations are unknown on first visits
Resident Evil 7: Biohazard leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Resident Evil 7: Biohazard
Resource crafting, tape management and route sequencing 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.
