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

Optimization · Pure Optimization
A logic puzzler about coordinating two characters with opposing interaction rules.

Optimization · Pure Optimization
A knowledge-based mystery solved by mapping a deterministic solar system.
About Love, Hate and the other ones 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.
About Love, Hate and the other ones
Minor timing on character movement, never twitch-defining
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.
About Love, Hate and the other ones
Solo puzzler - no opponent to predict
Outer Wilds
World is fixed; nothing adapts to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
About Love, Hate and the other ones
Behaviours are fixed once learned, nothing random
Outer Wilds
Loop is deterministic once understood
Outer Wilds leans a little harder on optimization, though the gap is small.
About Love, Hate and the other ones
Solving each level's logic puzzle is the entire game
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.
