head to head
Metroid: Other M 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 linear, cinematic Metroid mixing third-person action with first-person aiming.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Metroid: Other M leans Execution (Practiced Mastery).
Metroid: Other M leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Metroid: Other M
Dodge-timing and pointer-switch finishers
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
Metroid: Other M
Bosses run scripted patterns
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
Metroid: Other M
Linear, deterministic encounters
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
Metroid: Other M
Learning boss movesets and item routes
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.
