head to head
Resident Evil 4 asks more than Grand Theft Auto V, and the gap is execution.

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

Execution · Practiced Mastery
An action-survival loop driven by practiced crowd-control shooting and weapon-upgrade optimisation.
Grand Theft Auto V leans Execution (Practiced Mastery); Resident Evil 4 leans Execution (Practiced Mastery).
Resident Evil 4 leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Resident Evil 4
Crowd management requires precise, fast shooting under constant pressure
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 4
Ganados follow scripted group patterns, not player modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Some mission and lobby randomness.
Resident Evil 4
Minor drop RNG from enemies but encounters are fixed
Resident Evil 4 leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Resident Evil 4
Weapon upgrading, positioning and merchant economy are solvable
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.
