head to head
Metroid Fusion 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
Tense, linear Metroid hunted through a station by a clone of yourself.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Metroid Fusion leans Execution (Practiced Mastery).
Metroid Fusion leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Metroid Fusion
demanding bosses for a 2D Metroid
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 Fusion
SA-X stalking runs on fixed scripts
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 Fusion
first-encounter dread fades once mapped
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 Fusion
guided structure still rewards route and pattern knowledge
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.
