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
Medieval city-builder with light tactical battles; optimization first.

Optimization · Pure Optimization
Engineer a pandemic; evolution order is the puzzle.
Manor Lords leans Optimization (Pure Optimization); Plague Inc: Evolved leans Optimization (Pure Optimization).
Manor Lords leans a little harder on execution, though the gap is small.
Manor Lords
light battle micro
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.
Manor Lords
scripted bandit/AI raids
Plague Inc: Evolved
world response scripted
Plague Inc: Evolved leans a little harder on variance, though the gap is small.
Manor Lords
seasons, fertility, raids timing
Plague Inc: Evolved
country event timing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Manor Lords
burgage plots and supply chains central
Plague Inc: Evolved
evolution order heavily solved
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.
