head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
A classic psychological adventure where an amnesiac navigates surreal delusions to recover his identity.

Optimization · Pure Optimization
Balancing social energies and economy in a simplified city-planning sandbox.
Sanitarium leans Optimization (Pure Optimization); SimCity Societies 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.
Sanitarium
Point-and-click navigation requires no dexterity
SimCity Societies
Placing buildings has no physical demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sanitarium
No opponents; the delusions follow a fixed narrative
SimCity Societies
No opponent of any kind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sanitarium
Surreal puzzle logic is unknown until reasoned out
SimCity Societies
Occasional events, otherwise deterministic simulation
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sanitarium
Every chapter is a deterministic puzzle to solve
SimCity Societies
Balancing societal values and economy is the entire 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.
