PortalvsThe House of Da Vinci
Neither is simply harder - they are hard in different places. Portal demands more execution; The House of Da Vinci demands more variance.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
The House of Da Vinci
Optimization · Pure Optimization
A Room-style 3D puzzle box game set in Leonardo da Vinci's workshop of intricate contraptions.
Portal leans Optimization (Pure Optimization); The House of Da Vinci leans Optimization (Pure Optimization).
PortalThe House of Da Vinci
Axis by axis
Execution4 vs 1
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
The House of Da Vinci
Light touch manipulation of mechanisms; trivial precision.
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.
The House of Da Vinci
No adaptive opposition exists.
Variance0 vs 3
The House of Da Vinci leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
The House of Da Vinci
Hidden compartments and unknown contraptions; converges after discovery.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
Pure puzzle-solving optimization.
The House of Da Vinci
Solving fixed clockwork mechanisms is the entire test.
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.
