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

Optimization · Light / Casual
A disturbing point-and-click horror adventure satirizing 1950s Americana.

Variance · Light / Casual
A choice-driven comedy adventure with almost no skill test at all.
Harvester leans Optimization (Light / Casual); Tales from the Borderlands leans Variance (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Harvester
minimal physical skill, adventure exploration
Tales from the Borderlands
Occasional QTEs are the only physical demand
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
Tales from the Borderlands
No opponent of any kind
Tales from the Borderlands leans a little harder on variance, though the gap is small.
Harvester
negligible randomness
Tales from the Borderlands
Story branches are unknown until chosen
Harvester leans a little harder on optimization, though the gap is small.
Harvester
linear puzzle-adventure logic
Tales from the Borderlands
Choices barely change outcomes; nothing to solve
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.
