head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Systems & Chaos
A point-and-click adventure where a stolen painting drags George and Nico into a Gnostic conspiracy.

Optimization · Systems & Chaos
A horror visual novel testing careful choice-mapping to avoid hidden bad endings.
Broken Sword 5: The Serpent's Curse leans Optimization (Systems & Chaos); Corpse Party: Book of Shadows leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword 5: The Serpent's Curse
Click-driven; no manual skill ceiling.
Corpse Party: Book of Shadows
Visual-novel navigation needs only reading
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword 5: The Serpent's Curse
Gnostic conspiracy unfolds on rails.
Corpse Party: Book of Shadows
No adaptive opponent in the cursed school
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword 5: The Serpent's Curse
Art-theft mystery hides its heretical secret initially.
Corpse Party: Book of Shadows
Wrong-end triggers are hidden until discovered
Broken Sword 5: The Serpent's Curse leans a little harder on optimization, though the gap is small.
Broken Sword 5: The Serpent's Curse
Modern hint-friendly puzzles with fixed intended solutions.
Corpse Party: Book of Shadows
Mapping flags and choices to endings is the only system
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.
