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
Island colonisation strategy about balancing population tiers against expanding supply chains.

Optimization · Pure Optimization
A survival city builder driven by harsh resource and law optimization.
Anno 1602 leans Optimization (Pure Optimization); Frostpunk leans Optimization (Pure Optimization).
Anno 1602 leans a little harder on execution, though the gap is small.
Anno 1602
Slow real-time pace; no dexterity test.
Frostpunk
Pausable strategy with no input precision.
Anno 1602 leans a little harder on reads, though the gap is small.
Anno 1602
AI rivals act on fixed personalities, not adaptation.
Frostpunk
No adaptive opponent in the survival city.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1602
Island fertility layouts and rival starts are hidden initially.
Frostpunk
Scenario events and weather pulses add tension.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1602
Population tiers and supply chains are a near-pure logistics solve.
Frostpunk
Resource routing, laws, and heat are solvable.
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.
