head to head
Super Mario World 2: Yoshi's Island 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
A pastel platformer where Yoshi carries Baby Mario and perfect scores demand finding everything.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Super Mario World 2: Yoshi's Island leans Execution (Practiced Mastery).
Super Mario World 2: Yoshi's Island leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Super Mario World 2: Yoshi's Island
Egg-aiming and flutter jumps for 100 percent scores
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
Super Mario World 2: Yoshi's Island
All enemies are scripted
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
Super Mario World 2: Yoshi's Island
Collectibles hidden only until found
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
Super Mario World 2: Yoshi's Island
Perfect-score runs demand full collectible routing
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.
