Tales of Zestiria asks more than Portal, and the gap is variance.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.

Optimization · Pure Optimization
A fantasy JRPG whose infamous equipment fusion system dominates its skill test.
Portal leans Optimization (Pure Optimization); Tales of Zestiria 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.
Portal
Portal placement timing modest.
Tales of Zestiria
Armatization combat needs timing but forgives sloppiness
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal

Tales of Zestiria
Scripted hellion AI never adapts
Tales of Zestiria leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
Tales of Zestiria
Equipment skill randomness obscures ideal gear briefly
Portal leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Tales of Zestiria
Skill-fusion equipment stacking is a notorious optimization rabbit hole
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.
