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.

Optimization · Pure Optimization
Solving fixed 2D guard layouts through precise sound management and upgrade-optimised routing.

Optimization · Pure Optimization
The co-op sequel where two players engineer overlapping trap gauntlets against orc waves.
Mark of the Ninja leans Optimization (Pure Optimization); Orcs Must Die! 2 leans Optimization (Pure Optimization).
Mark of the Ninja leans a little harder on execution, though the gap is small.
Mark of the Ninja
Precise ledge timing, sound-cone avoidance, and kill windows demand input
Orcs Must Die! 2
Co-op shooting and trap triggering
Mark of the Ninja leans a little harder on reads, though the gap is small.
Mark of the Ninja
Guards investigate noise on scripted logic; no player profiling
Orcs Must Die! 2
Scripted wave pathing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mark of the Ninja
Guard placements are fixed per level; no RNG disrupts routing
Orcs Must Die! 2
Endless mode shuffles compositions slightly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mark of the Ninja
Distraction sequencing, upgrade paths, and ghost-score routing are solvable
Orcs Must Die! 2
Upgrade spirit economy and trap synergies dominate
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.
