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

Variance · Systems & Chaos
A short horror walk that tests little beyond finding fixed clues under scripted scares.

Variance · Systems & Chaos
Map-and-compass navigation through hidden dangers on a hostile mountain.
Don't Knock Twice leans Variance (Systems & Chaos); Kholat leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Knock Twice
Walking and grabbing objects - no dexterity test
Kholat
Walking the mountain takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Knock Twice
The witch follows scripted triggers, not an adapting mind
Kholat
The presence stalks on randomised triggers, not a mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Knock Twice
Scares and clue placement are unknown until experienced
Kholat
Navigating by map coordinates with hidden danger zones
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Knock Twice
Puzzle solutions and routes are fixed once learned
Kholat
Landmark navigation and route memory converge with repetition
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.
