head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
A PS2 driving simulator centred on mastering tracks and tuning cars through events.

Execution · Practiced Mastery
Movement execution and route optimisation through a fixed, mappable planet.
Gran Turismo 3: A-Spec leans Execution (Practiced Mastery); Super Metroid leans Execution (Practiced Mastery).
Gran Turismo 3: A-Spec leans a little harder on execution, though the gap is small.
Gran Turismo 3: A-Spec
Lap precision against the clock is the core test
Super Metroid
Wall-jumps, shinesparks and boss dodges demand precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 3: A-Spec
AI opponents never adapt
Super Metroid
Bosses cycle fixed patterns, never adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 3: A-Spec
Deterministic physics, minimal randomness
Super Metroid
Item and route knowledge is fixed once discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 3: A-Spec
Optimal cars, tunes, and racing lines are findable
Super Metroid
Sequence-breaking route optimisation is the enduring meta-game
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.
