head to head
Portal 2 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
A first-person puzzle game where seeing the solution is the whole skill.
Maquette leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
Maquette
Picking up objects has no dexterity requirement
Portal 2
Portal placement requires some precision but timing is lenient.
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 2
No opponent; puzzles are static.
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 2
Puzzles are deterministic with no randomness.
Portal 2 leans clearly harder on optimization.
Maquette
Deducing the correct object size and placement to use the recursive scale mechanic
Portal 2
Solving the puzzle's logic IS the entire game.
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.
