head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
A knowledge-based mystery solved by mapping a deterministic solar system.

Optimization · Pure Optimization
Pure factory-layout optimization with no pressure, randomness or opponent.
Outer Wilds leans Optimization (Pure Optimization); Shapez leans Optimization (Pure Optimization).
Outer Wilds leans a little harder on execution, though the gap is small.
Outer Wilds
Light piloting, mostly forgiving
Shapez
Placing belts has no time pressure at all
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
World is fixed; nothing adapts to you
Shapez
No adversary exists anywhere
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
Loop is deterministic once understood
Shapez
The infinite map's shapes are mappable immediately
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Outer Wilds
Pure knowledge puzzle - solve the system
Shapez
Designing efficient cutting and merging factories IS the 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.
