Portal asks more than Syberia, and the gap is execution.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.

Optimization · Pure Optimization
A mechanical journey adventure solved by understanding the logic of its automaton-filled world.
Portal leans Optimization (Pure Optimization); Syberia leans Optimization (Pure Optimization).
PortalSyberia
Axis by axis
Execution4 vs 1
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
Syberia
Walking and clicking; zero reflex demand
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.
Syberia
NPCs follow scripted dialogue trees with no adaptive modelling
Variance0 vs 1
Syberia leans a little harder on variance, though the gap is small.
Portal
Deterministic chambers; no randomness.
Syberia
Linear journey with virtually no hidden-information surprises
Optimization8 vs 7
Portal leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Syberia
Mechanical clockwork puzzles require mapping part relationships
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.
