head to head
Visage asks more than Firewatch, and the gap is variance.

Optimization · Light / Casual
A first-person mystery about a fire lookout in a Wyoming forest.

Variance · Light / Casual
A first-person psychological horror set in a cursed family home.
Firewatch leans Optimization (Light / Casual); Visage leans Variance (Light / Casual).
Visage leans a little harder on execution, though the gap is small.
Firewatch
Walking and radio dialogue only.
Visage
Slow movement and item use.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Firewatch
No adaptive opposition.
Visage
Ghosts follow scripted triggers.
Visage leans clearly harder on variance.
Firewatch
Minor environmental discoveries.
Visage
Some scares and item placements vary.
Visage leans a little harder on optimization, though the gap is small.
Firewatch
Few systems to optimize.
Visage
Sanity management is shallow.
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.
