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
A colonial-fantasy RPG won by faction routing and build optimization.

Optimization · Pure Optimization
Medieval economy RTS where feeding your army matters more than commanding it.
Greedfall leans Optimization (Pure Optimization); Knights and Merchants: The Shattered Kingdom leans Optimization (Pure Optimization).
Greedfall leans a little harder on execution, though the gap is small.
Greedfall
Lock-on action combat, modest demand
Knights and Merchants: The Shattered Kingdom
Manual troop formations need some real-time handling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Greedfall
Scripted enemy patterns
Knights and Merchants: The Shattered Kingdom
Campaign AI attacks on fixed triggers and timers.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Greedfall
Loot and check rolls
Knights and Merchants: The Shattered Kingdom
Enemy positions hidden until scouted, little else.
Knights and Merchants: The Shattered Kingdom leans a little harder on optimization, though the gap is small.
Greedfall
Faction routing, builds, crafting central
Knights and Merchants: The Shattered Kingdom
Food chains and serf logistics are the dominant solvable layer.
