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
Map-painting grand strategy ruled by mana and idea optimization.

Optimization · Pure Optimization
A turn-based tactics game about squad positioning in destructible WWII environments.
Europa Universalis IV leans Optimization (Pure Optimization); Silent Storm: Sentinels 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.
Europa Universalis IV
pausable, no twitch
Silent Storm: Sentinels
Turn-based, no physical aiming demands on player
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Europa Universalis IV
AI mostly scripted, some MP
Silent Storm: Sentinels
AI scripted but tactical positioning resembles light prediction
Silent Storm: Sentinels leans a little harder on variance, though the gap is small.
Europa Universalis IV
events, mission paths
Silent Storm: Sentinels
Hit chances and destructible cover add real randomness
Europa Universalis IV leans a little harder on optimization, though the gap is small.
Europa Universalis IV
idea groups, economy, mana spending
Silent Storm: Sentinels
Squad builds, positioning and turn economy decide battles
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.
