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 3D factory-building puzzle where spatial reasoning and throughput efficiency are the entire challenge.

Optimization · Pure Optimization
A knowledge-based mystery solved by mapping a deterministic solar system.
Infinifactory 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.
Infinifactory
Block placement has no timing pressure
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.
Infinifactory
No opponent; alien factory puzzle game
Outer Wilds
World is fixed; nothing adapts to you
Outer Wilds leans a little harder on variance, though the gap is small.
Infinifactory
Build targets are 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.
Infinifactory
Engineering 3D factory lines that assemble alien products correctly and efficiently
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.
