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
Sci-fi horror RPG blending Squaresoft turn systems with real-time dodging in 1997 Manhattan.
Metro 2033 leans Execution (Practiced Mastery); Parasite Eve 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
Active-time dodging between attack windows
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
Mitochondrial monsters follow fixed scripts
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
Random drops and first-run boss surprises
Parasite Eve leans a little harder on optimization, though the gap is small.
Metro 2033
ammo-as-currency economy and stealth routing
Parasite Eve
Weapon tuning and Parasite Energy management
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.
