head to head
Need for Speed III: Hot Pursuit 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
Arcade driving precision on memorised tracks while scripted cops chase.
Grand Theft Auto V leans Execution (Practiced Mastery); Need for Speed III: Hot Pursuit leans Execution (Practiced Mastery).
Need for Speed III: Hot Pursuit leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Need for Speed III: Hot Pursuit
Clean cornering at top speed is the entire skill test
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.
Need for Speed III: Hot Pursuit
Cops and rivals run scripted rubber-band behaviour
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.
Need for Speed III: Hot Pursuit
Traffic and cop placement vary mildly per race
Need for Speed III: Hot Pursuit leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Need for Speed III: Hot Pursuit
Tracks are fixed; ideal lines 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.
