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
Remake of Gaiden with dual protagonists and explorable dungeons.

Optimization · Systems & Chaos
A pixel-art horror fairy tale where a boy explores a cursed castle to win a kobold's inheritance.
Fire Emblem Echoes: Shadows of Valentia leans Optimization (Pure Optimization); The Count Lucanor leans Optimization (Systems & Chaos).
The Count Lucanor leans a little harder on execution, though the gap is small.
Fire Emblem Echoes: Shadows of Valentia
Turn-based menus only
The Count Lucanor
Light stealth evasion needs only basic movement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem Echoes: Shadows of Valentia
Scripted enemies on both routes
The Count Lucanor
Castle monsters patrol fixed routes without adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fire Emblem Echoes: Shadows of Valentia
Hit RNG plus dungeon encounters
The Count Lucanor
Unknown castle secrets and endings on a blind run
Fire Emblem Echoes: Shadows of Valentia leans a little harder on optimization, though the gap is small.
Fire Emblem Echoes: Shadows of Valentia
Dual-army routing and class promotions
The Count Lucanor
Candle placement, puzzles, and ending routes are solvable
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.
