head to head
Scott Pilgrim vs. the World: The Game 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
Beat-em-up spacing and combos boosted by memorised stat and shop routes.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Scott Pilgrim vs. the World: The Game leans Execution (Practiced Mastery).
Scott Pilgrim vs. the World: The Game leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Scott Pilgrim vs. the World: The Game
Crowd control, spacing and combo timing carry fights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Scott Pilgrim vs. the World: The Game
Enemies and exes use fixed scripted patterns
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
Scott Pilgrim vs. the World: The Game
Shop items and drops add light run noise
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
Scott Pilgrim vs. the World: The Game
Stat grinding and shop knowledge trivialise later levels
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.
