head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Island colonisation strategy about balancing population tiers against expanding supply chains.

Optimization · Pure Optimization
A tactical RPG solved through long-horizon build and class planning.
Anno 1602 leans Optimization (Pure Optimization); Fire Emblem: Three Houses 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.
Anno 1602
Slow real-time pace; no dexterity test.
Fire Emblem: Three Houses
Menu-driven, no mechanical bar
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1602
AI rivals act on fixed personalities, not adaptation.
Fire Emblem: Three Houses
AI follows fixed aggression rules
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1602
Island fertility layouts and rival starts are hidden initially.
Fire Emblem: Three Houses
Hit rates and crit RNG affect runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1602
Population tiers and supply chains are a near-pure logistics solve.
Fire Emblem: Three Houses
Class routing and build planning dominates
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.
