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

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

Optimization · Pure Optimization
An economy and layout optimization puzzle about keeping a small simulated city solvent.
Graveyard Keeper leans Optimization (Pure Optimization); SimCity 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
SimCity
Pause-friendly building removes any physical test
SimCity leans a little harder on reads, though the gap is small.
Graveyard Keeper
Villagers run on fixed schedules
SimCity
Region multiplayer is cooperative, not adversarial prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Graveyard Keeper
Minor drop randomness
SimCity
Disasters and agent simulation quirks add mild randomness
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
SimCity
Zoning, traffic flow and specialisation economies are the whole game
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.
