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 · Pure Optimization
Macabre management sim about running a medieval cemetery as a business.

Optimization · Pure Optimization
A farm-life sim solved by season routing and profit optimization.
Graveyard Keeper leans Optimization (Pure Optimization); Stardew Valley leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Graveyard Keeper
Light action farming inputs
Stardew Valley
Trivial timing on fishing and combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Graveyard Keeper
Villagers run on fixed schedules
Stardew Valley
No adaptive opponent exists
Stardew Valley leans a little harder on variance, though the gap is small.
Graveyard Keeper
Minor drop randomness
Stardew Valley
Crop luck and geode RNG matter modestly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Graveyard Keeper
Sprawling tech trees and grind-route efficiency
Stardew Valley
Routing seasons, profit loops, and bundles dominates
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.
