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
Grand strategy and line-infantry battles across the Napoleonic Wars.

Optimization · Pure Optimization
A tactical RPG testing positioning and turn prediction on a grid battlefield.
Napoleon: Total War leans Optimization (Pure Optimization); Vandal Hearts II leans Optimization (Pure Optimization).
Napoleon: Total War leans a little harder on execution, though the gap is small.
Napoleon: Total War
Real-time battle micro under pressure
Vandal Hearts II
Simultaneous-turn combat has no twitch input
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Napoleon: Total War
Multiplayer battles involve feints; campaign AI is mappable
Vandal Hearts II
Predicting AI move order matters but follows scripts
Vandal Hearts II leans a little harder on variance, though the gap is small.
Napoleon: Total War
Morale swings and fog of war
Vandal Hearts II
Hit chances add bounded randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Napoleon: Total War
Campaign economy, army composition, and line tactics
Vandal Hearts II
Unit positioning, builds and the prediction system win 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.
