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
The first Dishonored: a stealth-action playground of layered powers.

Optimization · Pure Optimization
A pirate-themed action RPG sequel trading Gothic gloom for muskets, voodoo, and tropical islands.
Dishonored leans Optimization (Practiced Mastery); Risen 2: Dark Waters leans Optimization (Pure Optimization).
Dishonored leans a little harder on execution, though the gap is small.
Dishonored
Blink timing and combat inputs matter.
Risen 2: Dark Waters
Clunky melee with dirty-trick interrupts; modest demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dishonored
Guard AI scripted, non-adaptive.
Risen 2: Dark Waters
Scripted enemy behavior throughout
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dishonored
Patrol timings vary mildly.
Risen 2: Dark Waters
Light loot randomness only
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dishonored
Power combos and stealth routes solvable.
Risen 2: Dark Waters
Skill investment, voodoo builds, and quest order decide power
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.
