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

Optimization · Light / Casual
A classic point-and-click adventure where time-travel puzzle logic is the entire challenge.

Optimization · Light / Casual
A first-person mystery about a fire lookout in a Wyoming forest.
Day of the Tentacle Remastered leans Optimization (Light / Casual); Firewatch 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.
Day of the Tentacle Remastered
no physical skill, point-and-click
Firewatch
Walking and radio dialogue only.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Day of the Tentacle Remastered
no opponents, puzzle-driven
Firewatch
No adaptive opposition.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Day of the Tentacle Remastered
no meaningful randomness
Firewatch
Minor environmental discoveries.
Day of the Tentacle Remastered leans a little harder on optimization, though the gap is small.
Day of the Tentacle Remastered
time-travel puzzle logic is solvable
Firewatch
Few systems to optimize.
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.
