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

A walking simulator piecing together a vanished English village's final days.

Optimization · Light / Casual
A first-person exploration about returning to an empty family home.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Everybody's Gone to the Rapture
Walking is the only verb
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.
Everybody's Gone to the Rapture
No opponent
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.
Everybody's Gone to the Rapture
Story fragments hidden until found
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.
Everybody's Gone to the Rapture
Light exploration completion at most
Gone Home
Order of discovery hardly matters.
