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.

Execution · Practiced Mastery
A co-op brawler testing modest combat execution and straightforward build progression.

Execution · Practiced Mastery
A twin-stick survival game testing base-layout economy and sustained horde aim.
The Lord of the Rings: War in the North leans Execution (Practiced Mastery); Yet Another Zombie Defense leans Execution (Practiced Mastery).
Yet Another Zombie Defense leans a little harder on execution, though the gap is small.
The Lord of the Rings: War in the North
Melee timing and crit windows reward active hands
Yet Another Zombie Defense
Twin-stick aim under swelling night hordes carries survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Lord of the Rings: War in the North
Orc hordes are scripted spawns, no adaptation
Yet Another Zombie Defense
Zombies beeline mindlessly, never adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Lord of the Rings: War in the North
Loot drops roll randomly across runs
Yet Another Zombie Defense
Wave composition varies modestly between runs
Yet Another Zombie Defense leans a little harder on optimization, though the gap is small.
The Lord of the Rings: War in the North
Class skill trees and co-op role gearing
Yet Another Zombie Defense
Turret placement and barricade economy decide how long you last
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.
