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 historical strategy game blending Bronze Age empire-building with mythic warfare.

Optimization · Pure Optimization
Map-painting grand strategy ruled by mana and idea optimization.
A Total War Saga: Troy 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.
A Total War Saga: Troy
minimal direct manual skill, command-driven
Europa Universalis IV
pausable, no twitch
A Total War Saga: Troy leans a little harder on reads, though the gap is small.
A Total War Saga: Troy
human multiplayer opponents bluff strategies
Europa Universalis IV
AI mostly scripted, some MP
Europa Universalis IV leans a little harder on variance, though the gap is small.
A Total War Saga: Troy
minor battle randomness and morale swings
Europa Universalis IV
events, mission paths
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Total War Saga: Troy
deep economy, tech, and battle-formation mastery
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.
