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

Optimization · Practiced Mastery
The 1992 survival-horror pioneer trapping you in a puzzle-filled haunted mansion.

Optimization · Practiced Mastery
Wordless environmental puzzle decoding in a hostile world, with minimal combat demands.
Alone in the Dark leans Optimization (Practiced Mastery); Scorn leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Alone in the Dark
Clunky combat and dodging
Scorn
Clunky combat exists but avoidance usually suffices
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alone in the Dark
Monsters scripted in place
Scorn
Creatures wander on simple scripts, never adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alone in the Dark
Traps surprise exactly once
Scorn
Opaque machinery puzzles are hidden logic until decoded
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alone in the Dark
Puzzle solutions and item routes are fixed
Scorn
Deciphering each biomechanical puzzle has one fixed solution
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.
