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

Execution · Practiced Mastery
Claustrophobic post-apocalyptic shooter where bullets double as currency.

Optimization · Practiced Mastery
A survival horror RPG blending real-time gunplay with tight ammo and build management.
Metro 2033 leans Execution (Practiced Mastery); Parasite Eve II leans Optimization (Practiced Mastery).
Metro 2033 leans a little harder on execution, though the gap is small.
Metro 2033
scarce-ammo gunfights punish sloppy aim
Parasite Eve II
Real-time aiming, dodging, and tank-control positioning.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metro 2033
mutants and bandits follow scripts
Parasite Eve II
Creatures attack on fixed patterns.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metro 2033
hidden moral points and supplies first run
Parasite Eve II
Unknown encounters and item placement first run.
Parasite Eve II leans a little harder on optimization, though the gap is small.
Metro 2033
ammo-as-currency economy and stealth routing
Parasite Eve II
Ammo economy, parasite energy builds, and routing reward planning.
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.
