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

Execution · Practiced Mastery
A nanosuit-powered FPS where you choose between cloaked stealth and armored assault through a ruined New York.

Execution · Pure Mechanics
A top-down shoot-em-up testing aim and dodging against scripted alien waves.
Crysis 2 leans Execution (Practiced Mastery); Earth Defense Force leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crysis 2
Aimbot trivialises every firefight; aim and movement carry it
Earth Defense Force
Top-down shooting and dodging are the core demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crysis 2
Scripted Ceph and soldiers follow fixed patterns
Earth Defense Force
Enemies are scripted waves, not adaptive
Earth Defense Force leans a little harder on variance, though the gap is small.
Crysis 2
Mostly known encounters with mild patrol randomness
Earth Defense Force
Enemy spawn patterns add some unpredictability
Crysis 2 leans a little harder on optimization, though the gap is small.
Crysis 2
Suit energy management and choosing stealth-versus-armor approaches
Earth Defense Force
Weapon management and positioning aid survival
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.
