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.

Optimization · Systems & Chaos
Planning stealthy escapes through randomised castle layouts with primitive controls.

Optimization · Practiced Mastery
Routing efficient digs and upgrades through a randomised mine.
Castle Wolfenstein leans Optimization (Systems & Chaos); SteamWorld Dig leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Castle Wolfenstein
Clunky aiming and movement demand care, not twitch
SteamWorld Dig
Digging and platforming need modest precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Castle Wolfenstein
Guards react by simple rules, never modelling you
SteamWorld Dig
Enemies follow simple fixed patterns
Castle Wolfenstein leans a little harder on variance, though the gap is small.
Castle Wolfenstein
Randomised castle layouts and chest contents reshape each escape
SteamWorld Dig
Randomised mine layouts hide ore and hazards each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Castle Wolfenstein
Stealth routes, uniforms and ammo economy are plannable
SteamWorld Dig
Upgrade routing and efficient dig paths drive progress
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.
