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 · Pure Optimization
An optimisation puzzle about historical pathfinding against variable events.

Optimization · Pure Optimization
Lane defense classic about managing a sun economy against shambling waves.
Humankind leans Optimization (Pure Optimization); Plants vs. Zombies leans Optimization (Pure Optimization).
Humankind leans a little harder on execution, though the gap is small.
Humankind
Micro-management speed matters little; macro is king.
Plants vs. Zombies
Clicking to plant, minimal pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Humankind
AI opponents lack true adaptation; no human element.
Plants vs. Zombies
Zombie waves follow set compositions
Humankind leans a little harder on variance, though the gap is small.
Humankind
Era choices and event randomness create replayability.
Plants vs. Zombies
Wave timing and lane pressure vary mildly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Humankind
Dominating systems and cultures is a deep optimisation puzzle.
Plants vs. Zombies
Sun economy and lane setups are near-solvable
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.
