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 · Pure Optimization
Designing a functional prison where security infrastructure and inmate need management prevent catastrophic failure.

Optimization · Pure Optimization
Scheduling scarce time and resources across a base run by copies of yourself.
Prison Architect leans Optimization (Pure Optimization); The Alters leans Optimization (Pure Optimization).
Prison Architect leans a little harder on execution, though the gap is small.
Prison Architect
Layout design is deliberate; no twitch demands
The Alters
Third-person walking and menus, no twitch demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Prison Architect
Prisoner behaviour is scripted around needs and contraband rules
The Alters
No adaptive opponent, only systems and story beats
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Prison Architect
Riots and smuggling attempts introduce meaningful hidden threats
The Alters
Unscouted events and alter reactions surprise first runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Prison Architect
Guard routing, cell ratios, and utility networks are deeply solvable
The Alters
Time, resource and crew scheduling under deadlines is the 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.
