head to head
Real Racing 3 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
Tests racing-line discipline and upgrade economy management on fixed real-world circuits.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Real Racing 3 leans Execution (Practiced Mastery).
Real Racing 3 leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Real Racing 3
Braking points and racing lines are pure motor skill
Real Racing 3 leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Real Racing 3
Time-shifted opponents are recordings, not adapting minds
Grand Theft Auto: San Andreas leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Real Racing 3
Tracks are licensed and fully fixed
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
Real Racing 3
Car upgrades and the monetised economy demand managing
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.
