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

Optimization · Pure Optimization
A lane-defense strategy game about timing economy and unit upgrades.

Optimization · Pure Optimization
Map-painting grand strategy ruled by mana and idea optimization.
Age of War 2 leans Optimization (Pure Optimization); Europa Universalis IV 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.
Age of War 2
Clicking to deploy units, no twitch precision
Europa Universalis IV
pausable, no twitch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Age of War 2
Mostly versus AI; minimal opponent adaptation
Europa Universalis IV
AI mostly scripted, some MP
Europa Universalis IV leans a little harder on variance, though the gap is small.
Age of War 2
Little hidden randomness in unit outcomes
Europa Universalis IV
events, mission paths
Europa Universalis IV leans a little harder on optimization, though the gap is small.
Age of War 2
Economy timing and unit composition through the ages decides wins
Europa Universalis IV
idea groups, economy, mana spending
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.
