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

Execution · Pure Mechanics
A survival arena shooter where raw execution against memorised escalating enemy waves defines how long you last.

Execution · Pure Mechanics
Arcade run-and-gun whose one-credit clears demand total spawn memorization and twitch.
Devil Daggers leans Execution (Pure Mechanics); Metal Slug 3 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Devil Daggers
Pure survival time depends on flawless movement and dagger precision
Metal Slug 3
one-hit deaths demand frame-level dodging and aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Devil Daggers
Spider AI and homing skulls are scripted; no adaptive opponent
Metal Slug 3
every enemy wave is scripted
Devil Daggers leans a little harder on variance, though the gap is small.
Devil Daggers
Enemy spawn waves escalate on a fixed timer with some positional variance
Metal Slug 3
branching paths vary runs slightly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Devil Daggers
Dagger upgrade timing and crowd-control positioning are learnable strategies
Metal Slug 3
memorizing spawns is the path to a one-credit clear
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.
