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
Optimising a dwarf fortress economy against a randomly generated world.

Optimization · Systems & Chaos
Managing willpower resources and armor-strip sequencing under narrative-driven attrition.
Craft the World leans Optimization (Pure Optimization); The Banner Saga leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Craft the World
Indirect dwarf orders mean hands barely matter
The Banner Saga
Turn-based; willpower spend timing is the sole execution nuance
The Banner Saga leans a little harder on reads, though the gap is small.
Craft the World
Monster waves follow predictable scripted triggers
The Banner Saga
AI follows predictable threat-targeting logic
The Banner Saga leans a little harder on variance, though the gap is small.
Craft the World
Random world generation hides resources until dug out
The Banner Saga
Armor/strength interaction and random narrative outcomes create variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Craft the World
Fortress layout, tech tree and crafting chains are the real game
The Banner Saga
Willpower economy and armor-strip sequencing are learnable solutions
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.
