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

Optimization · Light / Casual
A first-person fjord mystery from the 1920s solved by wandering, reading and talking to your companion.

Optimization · Light / Casual
A first-person exploration about returning to an empty family home.
Draugen leans Optimization (Light / Casual); Gone Home leans Optimization (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Draugen
Walking a fjord village; no dexterity.
Gone Home
Pure walking and inspection.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Draugen
No opponent; your companion is fully scripted.
Gone Home
No opponents.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Draugen
Fixed mystery; nothing randomised.
Gone Home
Notes and items are fixed.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Draugen
Light clue-gathering through documents and locations.
Gone Home
Order of discovery hardly matters.
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.
