head to head
Neither is simply harder - they are hard in different places. Ghostbusters: Sanctum of Slime demands more execution; The Witcher 3: Wild Hunt demands more optimization.

Execution · Practiced Mastery
A twin-stick shooter about aiming and matching weapons to scripted ghost waves.

Optimization · Practiced Mastery
A narrative action RPG where build planning matters more than reflex execution.
Ghostbusters: Sanctum of Slime leans Execution (Practiced Mastery); The Witcher 3: Wild Hunt leans Optimization (Practiced Mastery).
Ghostbusters: Sanctum of Slime leans clearly harder on execution.
Ghostbusters: Sanctum of Slime
Twin-stick aiming and dodging lead the combat
The Witcher 3: Wild Hunt
Combat timing matters but generous dodges forgive sloppy play.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ghostbusters: Sanctum of Slime
Ghost enemies follow scripted patterns, not adapting
The Witcher 3: Wild Hunt
Enemies use fixed AI behaviours; no adaptation.
Ghostbusters: Sanctum of Slime leans a little harder on variance, though the gap is small.
Ghostbusters: Sanctum of Slime
Enemy spawns and color-matching add some chaos
The Witcher 3: Wild Hunt
Loot rolls and minor combat variance only.
The Witcher 3: Wild Hunt leans clearly harder on optimization.
Ghostbusters: Sanctum of Slime
Matching weapon colors to enemies rewards planning
The Witcher 3: Wild Hunt
Builds, alchemy, and quest routing reward planning.
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.
