Human Resource MachinevsPortal
Neither is simply harder - they are hard in different places. Human Resource Machine demands more optimization; Portal demands more execution.
Human Resource Machine
Optimization · Pure Optimization
A visual programming puzzle that teaches algorithmic thinking through factory-floor instruction sequences.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Human Resource Machine leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Human Resource MachinePortal
Axis by axis
Execution1 vs 4
Portal leans clearly harder on execution.
Human Resource Machine
Dragging instructions has no timing component
Portal
Portal placement timing modest.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
No opponent; purely computational puzzle
Portal
No adversary modeling player.
Variance0 vs 0
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
Input data is fixed per level with no randomness
Portal
Deterministic chambers; no randomness.
Optimization10 vs 8
Human Resource Machine leans clearly harder on optimization.
Human Resource Machine
Writing minimal correct assembly-like programs to pass each input sequence
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.
