PortalvsReus
Neither is simply harder - they are hard in different places. Portal demands more execution; Reus demands more variance.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Reus
Optimization · Pure Optimization
A god game where four giants terraform a 2D planet and chain resource synergies to grow villages.
Portal leans Optimization (Pure Optimization); Reus leans Optimization (Pure Optimization).
PortalReus
Axis by axis
Execution4 vs 1
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
Reus
Slow giant movement; timing pressure is minimal
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.
Reus
Human villages follow predictable greed rules
Variance0 vs 2
Reus leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
Reus
Village ambitions inject mild randomness
Optimization8 vs 9
Reus leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Reus
Resource symbiosis chains are a deep solvable system
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.
