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
Time-looping sequel that doubles down on the swarm-shooting and weapon-farming loop.

Execution · Practiced Mastery
Claustrophobic post-apocalyptic shooter where bullets double as currency.
Earth Defense Force 6 leans Optimization (Practiced Mastery); Metro 2033 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.
Earth Defense Force 6
Swarm kiting and aim across four classes
Metro 2033
scarce-ammo gunfights punish sloppy aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Earth Defense Force 6
Enemies remain scripted swarm AI
Metro 2033
mutants and bandits follow scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Earth Defense Force 6
RNG weapon drops and armor farming
Metro 2033
hidden moral points and supplies first run
Earth Defense Force 6 leans a little harder on optimization, though the gap is small.
Earth Defense Force 6
Loadout theory and mission-specific strategies
Metro 2033
ammo-as-currency economy and stealth routing
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.
