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
Supernatural western turn-based tactics where a luck meter replaces pure hit-chance dice.

Optimization · Pure Optimization
Engineer a pandemic; evolution order is the puzzle.

Plague Inc: Evolved leans a little harder on execution, though the gap is small.
Hard West
Turn-based; no physical demands
Plague Inc: Evolved
no reflex
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hard West
AI follows fixed tactical scripts
Plague Inc: Evolved
world response scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hard West
Luck meter tames RNG but cards and shots vary
Plague Inc: Evolved
country event timing
Plague Inc: Evolved leans a little harder on optimization, though the gap is small.
Hard West
Positioning, ability combos, and luck-system math dominate
Plague Inc: Evolved
evolution order heavily solved
