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 surreal driving game of using light to guide giant creatures away.
Firewatch leans Optimization (Light / Casual); Titan Chaser leans Optimization (Light / Casual).
Titan Chaser leans a little harder on execution, though the gap is small.
Firewatch
Walking and radio dialogue only.
Titan Chaser
Driving and using light - low twitch demands
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.
Titan Chaser
Titans are scripted, not adaptive
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.
Titan Chaser
Fixed scenarios, minimal randomness
Titan Chaser leans a little harder on optimization, though the gap is small.
Firewatch
Few systems to optimize.
Titan Chaser
Figuring out how to herd each titan is the task
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.
