Portal asks more than Steins;Gate, and the gap is execution.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Steins;Gate
Optimization · Pure Optimization
A time-travel mystery where finding the correct sequence of phone interventions is the puzzle.
Portal leans Optimization (Pure Optimization); Steins;Gate leans Optimization (Pure Optimization).
PortalSteins;Gate
Axis by axis
Execution4 vs 0
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
Steins;Gate
Pure reading; phone choices are the only input
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.
Steins;Gate
No opponent; timeline branches are fixed
Variance0 vs 1
Steins;Gate leans a little harder on variance, though the gap is small.
Portal
Deterministic chambers; no randomness.
Steins;Gate
Phone trigger timing hides branch conditions until discovered
Optimization8 vs 4
Portal leans clearly harder on optimization.
Portal
Pure puzzle-solving optimization.
Steins;Gate
Mapping exact phone responses to unlock the True End is solvable
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.
