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

Optimization · Pure Optimization
A tactical RPG solved through long-horizon build and class planning.

Optimization · Pure Optimization
Pre-solving battles through ship design and deployment, then watching the answer play out.
Fire Emblem: Three Houses leans Optimization (Pure Optimization); Gratuitous Space Battles 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
