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
Managing a survivor community's economy and risk under permadeath randomness.
Ancestors: The Humankind Odyssey leans Optimization (Systems & Chaos); State of Decay 2 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
State of Decay 2
Combat is forgiving; stealth and swings need modest 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
State of Decay 2
Zombies and hostile NPCs follow randomised scripts
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
State of Decay 2
Permadeath, infestations and survivor traits randomise each community
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
State of Decay 2
Base building, resource routing and survivor management drive survival
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.
