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 · Practiced Mastery
Slow-burn revenge adventure built on daily routines, detective legwork, and QTEs in 1986 Yokosuka.

Optimization · Pure Optimization
A management game about ferrying spirits to the afterlife.
Shenmue leans Optimization (Practiced Mastery); Spiritfarer leans Optimization (Pure Optimization).
Shenmue leans a little harder on execution, though the gap is small.
Shenmue
QTEs and light brawling demand modest timing
Spiritfarer
Platforming is light and forgiving.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shenmue
NPCs run daily scripts; nothing adapts to you
Spiritfarer
Spirits follow scripted arcs.
Shenmue leans a little harder on variance, though the gap is small.
Shenmue
First playthrough leans on not knowing schedules and clues
Spiritfarer
Minor resource RNG.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Shenmue
Clue order, NPC schedules, and move training are fully mappable
Spiritfarer
Boat layout and crafting loops reward planning.
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.
