head to head
Grand Theft Auto: San Andreas asks more than Spider-Man: Shattered Dimensions, and the gap is optimization.

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

Execution · Practiced Mastery
A scripted action romp testing combat timing and memorised boss patterns.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Spider-Man: Shattered Dimensions leans Execution (Practiced Mastery).
Spider-Man: Shattered Dimensions leans a little harder on execution, though the gap is small.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Spider-Man: Shattered Dimensions
Combo timing and traversal demand moderate hands
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
Spider-Man: Shattered Dimensions
Bosses and enemies are fully scripted, never adaptive
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
Spider-Man: Shattered Dimensions
Linear levels with almost nothing hidden or random
Grand Theft Auto: San Andreas leans clearly harder on optimization.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Spider-Man: Shattered Dimensions
Upgrade choices and learning boss patterns carry the rest
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.
