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

Optimization · Practiced Mastery
A mining metroidvania about digging efficient tunnels, hauling ore, and compounding upgrades.

Optimization · Practiced Mastery
A narrative action RPG where build planning matters more than reflex execution.
SteamWorld Dig 2 leans Optimization (Practiced Mastery); The Witcher 3: Wild Hunt leans Optimization (Practiced Mastery).
SteamWorld Dig 2 leans a little harder on execution, though the gap is small.
SteamWorld Dig 2
Light platforming and digging dexterity
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.
SteamWorld Dig 2
Scripted enemies only
The Witcher 3: Wild Hunt
Enemies use fixed AI behaviours; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
SteamWorld Dig 2
Procedural ore pockets add mild run-to-run unknowns
The Witcher 3: Wild Hunt
Loot rolls and minor combat variance only.
SteamWorld Dig 2 leans a little harder on optimization, though the gap is small.
SteamWorld Dig 2
Dig routing, resource economy, and upgrade ordering are the game
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.
