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 · Systems & Chaos
A narrative race around an alternate steampunk world balancing routes, money, and time.

Optimization · Pure Optimization
Remake of Gaiden with dual protagonists and explorable dungeons.
80 Days leans Optimization (Systems & Chaos); Fire Emblem Echoes: Shadows of Valentia leans Optimization (Pure Optimization).
Fire Emblem Echoes: Shadows of Valentia leans a little harder on execution, though the gap is small.
80 Days
Menu choices only, no physical skill
Fire Emblem Echoes: Shadows of Valentia
Turn-based menus only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
80 Days
NPCs follow scripted branches, never adapt
Fire Emblem Echoes: Shadows of Valentia
Scripted enemies on both routes
80 Days leans a little harder on variance, though the gap is small.
80 Days
Unknown routes, events, and market prices on first runs
Fire Emblem Echoes: Shadows of Valentia
Hit RNG plus dungeon encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
80 Days
Routing, packing, and trading converge to optimal circumnavigations
Fire Emblem Echoes: Shadows of Valentia
Dual-army routing and class promotions
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.
