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.

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

Optimization · Practiced Mastery
Memorising and rapidly inputting spell recipes while dodging your own friends.
Dishonored leans Optimization (Practiced Mastery); Magicka 2 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.
Magicka 2
Typing element combos quickly mid-fight is the skill ceiling
Dishonored leans a little harder on reads, though the gap is small.
Dishonored
Guard AI scripted, non-adaptive.
Magicka 2
Enemies are scripted; friendly-fire chaos is not prediction
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.
Magicka 2
Co-op misfires add slapstick randomness, little else
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.
Magicka 2
Knowing the strongest spell recipes trivialises encounters
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.
