Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
A turn-based fantasy strategy game where economy and army optimization decide games.

Optimization · Pure Optimization
Engineer a pandemic; evolution order is the puzzle.
Might & Magic Heroes VII leans Optimization (Pure Optimization); Plague Inc: Evolved leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Plague Inc: Evolved
no reflex
Might & Magic Heroes VII leans a little harder on reads, though the gap is small.
Might & Magic Heroes VII
human opponents can be out-maneuvered strategically
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.
Might & Magic Heroes VII
combat rolls and map resource randomness
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.
Might & Magic Heroes VII
army building and economy optimization dominate
Plague Inc: Evolved
evolution order heavily solved
