head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Systems & Chaos
An evolutionary survival sim about guiding an ape lineage through ten million years.

Optimization · Systems & Chaos
Excavating a procedurally generated underground world and solving its layered boss and crafting progression.
Ancestors: The Humankind Odyssey leans Optimization (Systems & Chaos); Core Keeper leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Ancestors: The Humankind Odyssey
Climbing and dodge timing are forgiving
Core Keeper
Boss fights and melee require learned dodge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ancestors: The Humankind Odyssey
Predators act on instinct scripts
Core Keeper
All bosses and enemies are scripted with fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ancestors: The Humankind Odyssey
Systems deliberately unexplained until experimented
Core Keeper
World seed, ore placement, and loot drops are randomised
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ancestors: The Humankind Odyssey
Neuron routing and lineage planning dominate
Core Keeper
Mining routes, crafting progression, and boss order are systematic
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.
