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
A chaotic co-op action game where wizards combine eight elements into thousands of spells, often frying each other.

Execution · Practiced Mastery
Patient positioning and learned ballistics, executed one careful shot at a time.
Magicka leans Optimization (Practiced Mastery); Sniper Elite 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.
Magicka
Typing element combos quickly mid-combat is the hands test
Sniper Elite
Steadying long shots against wind and breathing demands precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Magicka
Enemies are scripted; friendly fire isn't adaptive
Sniper Elite
Enemy patrols follow scripts, not adaptive minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Magicka
Co-op friendly-fire chaos adds unpredictability
Sniper Elite
Guard positions are scripted-but-unknown on first pass
Magicka leans a little harder on optimization, though the gap is small.
Magicka
Discovering and exploiting spell combinations dominates
Sniper Elite
Ballistics math, positioning and route planning carry each mission
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.
