head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
The PS1 driving opus where picking and tuning the right car for each event matters as much as driving it.

Execution · Practiced Mastery
Movement execution and route optimisation through a fixed, mappable planet.
Gran Turismo 2 leans Execution (Practiced Mastery); Super Metroid leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 2
Clean braking and lines matter, aided by forgiving AI.
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 2
Rolling-start AI follows fixed pace scripts.
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 2
Used car lot rotation is minor 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 2
Car selection, tuning and prize-money routing dominate the career.
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.
