head to head
Geometry Wars 3: Dimensions asks more than DOOM (2016), and the gap is variance.

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
A twin-stick arcade shooter where relentless swarm pressure demands perfect movement and targeting at escalating pace.
DOOM (2016) leans Execution (Pure Mechanics); Geometry Wars 3: Dimensions 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.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Geometry Wars 3: Dimensions
Weaving geometric enemy swarms at extreme speed is the ceiling
DOOM (2016) leans a little harder on reads, though the gap is small.
DOOM (2016)
Demons scripted attack patterns.
Geometry Wars 3: Dimensions
No opponent; all enemy behaviour is scripted swarm logic
Geometry Wars 3: Dimensions leans clearly harder on variance.
DOOM (2016)
Minimal encounter randomness.
Geometry Wars 3: Dimensions
Enemy spawn positions vary run-to-run, adding chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Rune and weapon mod picks meaningful.
Geometry Wars 3: Dimensions
Drone type selection and geom farming locations are learnable
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.
