PortalStarbound
Axis by axis
Execution4 vs 3
Portal leans a little harder on execution, though the gap is small.
Portal
Portal placement timing modest.
Starbound
Light platforming and combat, generous margins
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.
Starbound
Procedural NPCs follow simple fixed behaviours
Variance0 vs 4
Starbound leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
Starbound
Procedural planets and loot keep early exploration unknown
Optimization8 vs 7
Portal leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Starbound
Gear tiers, farming, and progression routes dominate
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.
