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

Execution · Pure Mechanics
A gory budget FPS testing twitch aim through linear scripted firefights.

Execution · Practiced Mastery
Alt-history FPS pivoting between brutal combat and quiet moments.
Soldier of Fortune: Payback leans Execution (Pure Mechanics); Wolfenstein: The New Order 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.
Soldier of Fortune: Payback
Twitch gunfights against aggressive AI are the core
Wolfenstein: The New Order
Dual-wield shooting and movement demand inputs.
Soldier of Fortune: Payback leans a little harder on reads, though the gap is small.
Soldier of Fortune: Payback
Multiplayer existed but campaign AI never adapts
Wolfenstein: The New Order
Nazi AI scripted, predictable.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Soldier of Fortune: Payback
Linear levels hold few surprises
Wolfenstein: The New Order
Almost no randomness.
Wolfenstein: The New Order leans a little harder on optimization, though the gap is small.
Soldier of Fortune: Payback
Loadout picks add only a thin layer
Wolfenstein: The New Order
Perks and weapon upgrades light.
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.
