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

Optimization · Practiced Mastery
The first Dishonored: a stealth-action playground of layered powers.

Optimization · Practiced Mastery
Expanded machine combat with broader build systems and traversal tools.
Dishonored leans Optimization (Practiced Mastery); Horizon Forbidden West 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.
Dishonored
Blink timing and combat inputs matter.
Horizon Forbidden West
Faster combat with valor surges and aiming.
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.
Horizon Forbidden West
Machines remain scripted, not adaptive.
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.
Horizon Forbidden West
Loot rolls and patrol RNG light.
Dishonored leans a little harder on optimization, though the gap is small.
Dishonored
Power combos and stealth routes solvable.
Horizon Forbidden West
Deeper gear, weapon techniques, machine weaknesses.
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.
