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 · Systems & Chaos
Puzzle adventure about coaxing a giant half-tame creature through ancient ruins.

Optimization · Systems & Chaos
A wordless surreal exploration game about wandering a sleeping girl's dreamscapes.
The Last Guardian leans Optimization (Systems & Chaos); Yume Nikki leans Optimization (Systems & Chaos).
The Last Guardian leans a little harder on execution, though the gap is small.
The Last Guardian
Slow climbing and platforming, very forgiving
Yume Nikki
Just walking, no challenge on inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Last Guardian
Trico is willful but not modeling you adversarially
Yume Nikki
No opponent of any kind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Last Guardian
Trico's unpredictable compliance adds noise
Yume Nikki
Random events and obscure unknown triggers
The Last Guardian leans a little harder on optimization, though the gap is small.
The Last Guardian
Environmental puzzles with intended solutions
Yume Nikki
Mapping the dream worlds to find 24 effects
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.
