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

Optimization · Pure Optimization
A perspective-rotation platformer with a hidden cryptographic layer that rewards patient decoding.

Optimization · Pure Optimization
A knowledge-based mystery solved by mapping a deterministic solar system.
Fez leans Optimization (Pure Optimization); Outer Wilds leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fez
Rotation and platforming needs light precision only
Outer Wilds
Light piloting, mostly forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fez
No opponent; solo exploration puzzle
Outer Wilds
World is fixed; nothing adapts to you
Outer Wilds leans a little harder on variance, though the gap is small.
Fez
World is fixed and deterministic
Outer Wilds
Loop is deterministic once understood
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fez
Decoding the deep cipher system and spatial cube logic is the core challenge
Outer Wilds
Pure knowledge puzzle - solve the system
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.
