head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

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

Optimization · Light / Casual
A darkly satirical toy-burning game about feeding an endless fireplace.
Firewatch leans Optimization (Light / Casual); Little Inferno leans Optimization (Light / Casual).
Firewatch leans a little harder on execution, though the gap is small.
Firewatch
Walking and radio dialogue only.
Little Inferno
Drag items into a fire, that's it
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.
Little Inferno
No opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Firewatch
Minor environmental discoveries.
Little Inferno
Combo names hint at discoverable pairings
Little Inferno leans a little harder on optimization, though the gap is small.
Firewatch
Few systems to optimize.
Little Inferno
Finding burn combos is a light solvable layer
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.
