head to head
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
Optimizing custom race design and tech priorities across a randomly generated galaxy.

Optimization · Pure Optimization
Engineer a pandemic; evolution order is the puzzle.
Master of Orion (2016) 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.
Master of Orion (2016)
Turn-based menus; no physical demands at all
Plague Inc: Evolved
no reflex
Master of Orion (2016) leans a little harder on reads, though the gap is small.
Master of Orion (2016)
AI races follow defined personalities without adapting to your play
Plague Inc: Evolved
world response scripted
Master of Orion (2016) leans a little harder on variance, though the gap is small.
Master of Orion (2016)
Random galaxy generation and diplomatic outcomes add hidden elements
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.
Master of Orion (2016)
Race design, tech priorities, and fleet composition are the solvable core
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.
