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-RPG where build synergies and companion routing carry combat.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Dragon Age: The Veilguard 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.
Dragon Age: The Veilguard
Real-time action, dodge and parry windows
Portal
Portal placement timing modest.
Dragon Age: The Veilguard leans a little harder on reads, though the gap is small.
Dragon Age: The Veilguard
Scripted bosses, no adaptive opponents
Portal
No adversary modeling player.
Dragon Age: The Veilguard leans a little harder on variance, though the gap is small.
Dragon Age: The Veilguard
Minimal RNG in combat
Portal
Deterministic chambers; no randomness.
Portal leans a little harder on optimization, though the gap is small.
Dragon Age: The Veilguard
Builds, runes, companion synergies central
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.
