Yume Nikki leans a little harder on execution, though the gap is small.
Animal Crossing

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.
Animal Crossing
Villagers are charming scripts
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.
Animal Crossing
Random visitors, fossils, and villager moves
Yume Nikki
Random events and obscure unknown triggers
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Crossing
Debt payoff and collection routing, gently
Yume Nikki
Mapping the dream worlds to find 24 effects
