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

Optimization · Practiced Mastery
Peak PS2-era Ratchet, blending arsenal progression with polished combat arenas.
Mark of the Ninja leans Optimization (Pure Optimization); Ratchet & Clank: Up Your Arsenal leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mark of the Ninja
Precise ledge timing, sound-cone avoidance, and kill windows demand input
Ratchet & Clank: Up Your Arsenal
Faster combat demanding strafing and aim precision.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mark of the Ninja
Guards investigate noise on scripted logic; no player profiling
Ratchet & Clank: Up Your Arsenal
Campaign is scripted; legacy multiplayer added a thin PvP layer.
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
Ratchet & Clank: Up Your Arsenal
Unknown encounters only on first playthrough.
Mark of the Ninja leans a little harder on optimization, though the gap is small.
Mark of the Ninja
Distraction sequencing, upgrade paths, and ghost-score routing are solvable
Ratchet & Clank: Up Your Arsenal
Weapon XP, bolt economy, and route mastery decide everything.
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.
