head to head
Grand Theft Auto: San Andreas asks more than Angry Birds Go!, and the gap is optimization.

Execution · Practiced Mastery
A mobile kart racer testing simple line-holding against upgrade-gated progression.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Angry Birds Go! leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Angry Birds Go! leans a little harder on execution, though the gap is small.
Angry Birds Go!
Steering and boost timing decide downhill races
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Angry Birds Go! leans a little harder on reads, though the gap is small.
Angry Birds Go!
Opponent karts run rubber-band AI, nothing to model
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Go!
Power-up rolls inject mild chaos
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Angry Birds Go!
Kart upgrades and racing lines dominate progression
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
