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.

Optimization · Practiced Mastery
A cinematic stealth-action sequel raising the stakes and the rat tides.

Execution · Practiced Mastery
Claustrophobic post-apocalyptic shooter where bullets double as currency.
A Plague Tale: Requiem leans Optimization (Practiced Mastery); Metro 2033 leans Execution (Practiced Mastery).
Metro 2033 leans a little harder on execution, though the gap is small.
A Plague Tale: Requiem
Stealth, aim, and crafting under pressure.
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.
A Plague Tale: Requiem
Enemies use scripted behaviors.
Metro 2033
mutants and bandits follow scripts
Metro 2033 leans a little harder on variance, though the gap is small.
A Plague Tale: Requiem
Minor encounter variability.
Metro 2033
hidden moral points and supplies first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
A Plague Tale: Requiem
Tool combos solve set-piece encounters.
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.
