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 tactical RPG solved through long-horizon build and class planning.

Optimization · Pure Optimization
A farm-life sim solved by season routing and profit optimization.
Fire Emblem: Three Houses leans Optimization (Pure Optimization); Stardew Valley 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.
Fire Emblem: Three Houses
Menu-driven, no mechanical bar
Stardew Valley
Trivial timing on fishing and combat
Fire Emblem: Three Houses leans a little harder on reads, though the gap is small.
Fire Emblem: Three Houses
AI follows fixed aggression rules
Stardew Valley
No adaptive opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem: Three Houses
Hit rates and crit RNG affect runs
Stardew Valley
Crop luck and geode RNG matter modestly
Fire Emblem: Three Houses leans a little harder on optimization, though the gap is small.
Fire Emblem: Three Houses
Class routing and build planning dominates
Stardew Valley
Routing seasons, profit loops, and bundles 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.
