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 disturbing point-and-click horror adventure satirizing 1950s Americana.

Optimization · Light / Casual
An atmospheric narrative theatre piece where engagement is interpretive rather than problem-solving.
Harvester leans Optimization (Light / Casual); Kentucky Route Zero leans Optimization (Light / Casual).
Harvester leans a little harder on execution, though the gap is small.
Harvester
minimal physical skill, adventure exploration
Kentucky Route Zero
Player input amounts to clicking and dialogue selection only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Harvester
no adversarial adaptive opponent
Kentucky Route Zero
No opponent; choices shape tone not outcomes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Harvester
negligible randomness
Kentucky Route Zero
Negligible randomness; the world is a fixed authored space
Kentucky Route Zero leans a little harder on optimization, though the gap is small.
Harvester
linear puzzle-adventure logic
Kentucky Route Zero
There is no puzzle layer; the game resists solvability by design
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.
