head to head
Outer Wilds asks more than Return of the Obra Dinn, and the gap is execution.

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

Optimization · Pure Optimization
A pure deduction puzzle with a single solvable answer set.
Outer Wilds leans Optimization (Pure Optimization); Return of the Obra Dinn leans Optimization (Pure Optimization).
Outer Wilds leans clearly harder on execution.
Outer Wilds
Light piloting, mostly forgiving
Return of the Obra Dinn
No mechanical execution required
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
Return of the Obra Dinn
Static scenes, no opponent
Outer Wilds leans a little harder on variance, though the gap is small.
Outer Wilds
Loop is deterministic once understood
Return of the Obra Dinn
Fully deterministic puzzle
Return of the Obra Dinn leans a little harder on optimization, though the gap is small.
Outer Wilds
Pure knowledge puzzle - solve the system
Return of the Obra Dinn
Pure deductive logic on a fixed manifest
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.
