head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Mind & Math
Economy and formation optimisation at huge scale against adapting human strategy.

Optimization · Mind & Math
Tolkien RTS where build orders and army counters decide the war for Middle-earth.
Cossacks: European Wars leans Optimization (Mind & Math); The Lord of the Rings: The Battle for Middle-earth leans Optimization (Mind & Math).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Cossacks: European Wars
Managing thousands of units strains APM and attention
The Lord of the Rings: The Battle for Middle-earth
Micro and multitasking under real-time pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cossacks: European Wars
Human opponents shift compositions and timing attacks
The Lord of the Rings: The Battle for Middle-earth
Multiplayer rewards predicting opponent army choices
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cossacks: European Wars
Map resources and scouting gaps hide information early
The Lord of the Rings: The Battle for Middle-earth
Scouting hides enemy composition until revealed
Cossacks: European Wars leans a little harder on optimization, though the gap is small.
Cossacks: European Wars
Economy ratios, tech order and formation math dominate outcomes
The Lord of the Rings: The Battle for Middle-earth
Build orders and counter units are largely 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.
