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
A musou spinoff of Fire Emblem: Three Houses blending hack-and-slash combat with light tactics.

Optimization · Pure Optimization
A physics puzzle game about building wobbly towers and bridges from living goo balls.
Fire Emblem Warriors: Three Hopes leans Optimization (Pure Optimization); World of Goo leans Optimization (Pure Optimization).
Fire Emblem Warriors: Three Hopes leans a little harder on execution, though the gap is small.
Fire Emblem Warriors: Three Hopes
Real-time combat is forgiving hack-and-slash
World of Goo
Placing goo balls needs only mild precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem Warriors: Three Hopes
Enemy commanders follow scripted AI
World of Goo
No 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 Warriors: Three Hopes
Minor drop and recruitment randomness
World of Goo
Physics are visible and deterministic
World of Goo leans a little harder on optimization, though the gap is small.
Fire Emblem Warriors: Three Hopes
Class builds, unit orders, weapon triangle, map management decide battles
World of Goo
Tower structure and goo economy are solvable per level
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.
