head to head
Need for Speed III: Hot Pursuit asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
Arcade driving precision on memorised tracks while scripted cops chase.
Grand Theft Auto: San Andreas leans Optimization (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: San Andreas
Flying school and drive-bys need decent hands
Need for Speed III: Hot Pursuit
Clean cornering at top speed is the entire skill test
Need for Speed III: Hot Pursuit leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
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: San Andreas
Territory wars and traffic add light randomness
Need for Speed III: Hot Pursuit
Traffic and cop placement vary mildly per race
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
