Axis by axis
Execution4 vs 1
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
Sanitarium
Point-and-click navigation requires no dexterity
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
No adversary modeling player.
Sanitarium
No opponents; the delusions follow a fixed narrative
Variance0 vs 2
Sanitarium leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
Sanitarium
Surreal puzzle logic is unknown until reasoned out
Optimization8 vs 7
Portal leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Sanitarium
Every chapter is a deterministic puzzle to solve
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.
