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

Optimization · Practiced Mastery
Hybrid tower-defense testing maze optimization backed by first-person aim.
Magicka leans Optimization (Practiced Mastery); Sanctum 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.
Magicka
Typing element combos quickly mid-combat is the hands test
Sanctum 2
Weak-point shooting during waves carries real aim demands
Magicka leans a little harder on reads, though the gap is small.
Magicka
Enemies are scripted; friendly fire isn't adaptive
Sanctum 2
Alien waves path predictably toward the core
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
Sanctum 2
Wave compositions vary mildly between maps
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Magicka
Discovering and exploiting spell combinations dominates
Sanctum 2
Maze layouts and tower economics are the solvable heart
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.
