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
A dark-fantasy strategy RPG about building armies and winning turn-based battles.

Optimization · Pure Optimization
Engineer a pandemic; evolution order is the puzzle.
Disciples: Liberation 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.
Disciples: Liberation
Turn-based combat needs no input speed
Plague Inc: Evolved
no reflex
Disciples: Liberation leans a little harder on reads, though the gap is small.
Disciples: Liberation
AI uses fixed tactics; multiplayer adds light prediction
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.
Disciples: Liberation
Damage rolls and map encounters carry randomness
Plague Inc: Evolved
country event timing
Plague Inc: Evolved leans a little harder on optimization, though the gap is small.
Disciples: Liberation
Army composition, upgrades and tactical positioning decide battles
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.
