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
Engineer a pandemic; evolution order is the puzzle.

Optimization · Pure Optimization
A real-time tactics RPG where designing auto-combat unit formations and routing resource economy is the entire challenge.
Plague Inc: Evolved leans Optimization (Pure Optimization); Unicorn Overlord leans Optimization (Pure Optimization).
Unicorn Overlord leans a little harder on execution, though the gap is small.
Plague Inc: Evolved
no reflex
Unicorn Overlord
Real-time unit ordering has minimal twitch demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Plague Inc: Evolved
world response scripted
Unicorn Overlord
Enemy formation AI is scripted; no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Plague Inc: Evolved
country event timing
Unicorn Overlord
Hidden unit skills and mission branch outcomes add meaningful uncertainty
Unicorn Overlord leans a little harder on optimization, though the gap is small.
Plague Inc: Evolved
evolution order heavily solved
Unicorn Overlord
Unit formation design, tactic routing, and value economy are literally the game
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.
