head to head
Metroid: Zero Mission 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
Remake of the original Metroid with modern movement and a stealth epilogue.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Metroid: Zero Mission leans Execution (Practiced Mastery).
Metroid: Zero Mission leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Metroid: Zero Mission
polished 2D movement plus a stealth finale
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: Zero Mission
enemies and pirates are scripted
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
Metroid: Zero Mission
hidden passages unknown only once
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
Metroid: Zero Mission
sequence breaks and route optimization are celebrated
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.
