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 knowledge-based mystery solved by mapping a deterministic solar system.

Optimization · Pure Optimization
Puzzle sequel where glove powers paint blocks to solve physical room logic.
Outer Wilds leans Optimization (Pure Optimization); Q.U.B.E. 2 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.
Outer Wilds
Light piloting, mostly forgiving
Q.U.B.E. 2
Occasional timing on moving blocks only
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
Q.U.B.E. 2
No adaptive element exists
Outer Wilds leans a little harder on variance, though the gap is small.
Outer Wilds
Loop is deterministic once understood
Q.U.B.E. 2
Deterministic puzzles with full information
Outer Wilds leans a little harder on optimization, though the gap is small.
Outer Wilds
Pure knowledge puzzle - solve the system
Q.U.B.E. 2
Glove-power combinations resolve to clean solutions
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.
