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

Optimization · Pure Optimization
An action-ATB JRPG about stagger setups and materia loadout planning.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Final Fantasy VII Remake leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Final Fantasy VII Remake
Action timing matters but ATB pause forgives sloppy play.
Portal
Portal placement timing modest.
Final Fantasy VII Remake leans a little harder on reads, though the gap is small.
Final Fantasy VII Remake
Bosses use scripted phases; no genuine adaptation.
Portal
No adversary modeling player.
Final Fantasy VII Remake leans a little harder on variance, though the gap is small.
Final Fantasy VII Remake
Minor drop and materia growth randomness.
Portal
Deterministic chambers; no randomness.
Portal leans a little harder on optimization, though the gap is small.
Final Fantasy VII Remake
Materia loadouts and stagger windows are deeply solvable.
Portal
Pure puzzle-solving optimization.
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.
