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
Solving a civilisation-scale resource and governance puzzle before an ecological deadline.

Optimization · Pure Optimization
A tactical RPG solved through long-horizon build and class planning.
Eco 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.
Eco
No twitch element; all actions are build and craft clicks
Fire Emblem: Three Houses
Menu-driven, no mechanical bar
Eco leans a little harder on reads, though the gap is small.
Eco
Other players add mild human negotiation reads in multiplayer
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.
Eco
Meteor timer and ecosystem variables carry some hidden uncertainty
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.
Eco
Government systems, specialisation routing, and ecosystem management are richly solvable
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.
