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
Harsh village-builder; balance population, food, and winter.

Optimization · Pure Optimization
Optimizing regional economics and city services to sustain growth without collapsing your budget.
Banished leans Optimization (Pure Optimization); SimCity 4 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.
Banished
no mechanical layer
SimCity 4
Point-and-click placement; zero reflex requirement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Banished
no opponent
SimCity 4
Solo sandbox with no adversarial pressure
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Banished
weather, disease events
SimCity 4
Neighbor city interactions and demand curves add unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Banished
population ratios and food planning
SimCity 4
Budget, ordinances, and transport networks are the core puzzle
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.
