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
Namco's lavish Galaga sequel adds dimension warps and ship-stacking to classic formation shooting.

Execution · Practiced Mastery
A voxel-based arcade shooter where precise movement and optimal human-rescue sequencing drive score.
Galaga '88 leans Execution (Pure Mechanics); Resogun leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Galaga '88
Precise dodging and shooting through dense dive patterns.
Resogun
Precise overdrive timing and bullet-threading at high speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Galaga '88
Aliens attack on choreographed scripts.
Resogun
Scripted enemy formations only
Galaga '88 leans a little harder on variance, though the gap is small.
Galaga '88
Dive timing and dimension-warp triggers vary.
Resogun
Particle-based destruction and some randomised enemy entry points
Resogun leans a little harder on optimization, though the gap is small.
Galaga '88
Triple-ship management and warp routing reward planning.
Resogun
Keeper rescue sequencing and phase timing are fully 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.
