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 pure deduction puzzle with a single solvable answer set.

Optimization · Pure Optimization
A deeper extension of the original spatial logic with more elaborate multi-tool puzzles.
Return of the Obra Dinn leans Optimization (Pure Optimization); The Talos Principle 2 leans Optimization (Pure Optimization).
The Talos Principle 2 leans a little harder on execution, though the gap is small.
Return of the Obra Dinn
No mechanical execution required
The Talos Principle 2
Environmental traversal imposes negligible physical demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Return of the Obra Dinn
Static scenes, no opponent
The Talos Principle 2
No opponent; isolated puzzle solving throughout
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Return of the Obra Dinn
Fully deterministic puzzle
The Talos Principle 2
Puzzles are fully deterministic with no randomness
Return of the Obra Dinn leans a little harder on optimization, though the gap is small.
Return of the Obra Dinn
Pure deductive logic on a fixed manifest
The Talos Principle 2
Expanded connector and accumulator mechanics require exact logical sequencing
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.
