head to head
Portal asks more than Maquette, and the gap is execution.

Optimization · Pure Optimization
A recursive scale puzzle game where placing objects in the miniature affects the full-scale world.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Maquette leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans clearly harder on execution.
Maquette
Picking up objects has no dexterity requirement
Portal
Portal placement timing modest.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Maquette
No opponent; narrative-driven scale puzzle
Portal
No adversary modeling player.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Maquette
All scale puzzles are deterministic
Portal
Deterministic chambers; no randomness.
Portal leans a little harder on optimization, though the gap is small.
Maquette
Deducing the correct object size and placement to use the recursive scale mechanic
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.
