head to head
Zelda II: The Adventure of Link 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
The notoriously demanding side-scrolling Zelda built on tight sword duels and RPG levelling.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Zelda II: The Adventure of Link leans Execution (Practiced Mastery).
Zelda II: The Adventure of Link leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Zelda II: The Adventure of Link
Precise sword spacing, shield stabs, brutal platforming
Zelda II: The Adventure of Link leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Zelda II: The Adventure of Link
Ironknuckles feint but follow fixed logic
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
Zelda II: The Adventure of Link
Layouts fixed, little hidden randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Zelda II: The Adventure of Link
XP routing, spell use, palace order planning
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.
