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
Claustrophobic post-apocalyptic shooter where bullets double as currency.

Execution · Practiced Mastery
A first-person shooter campaign set in the future war of the Terminator films.
Metro 2033 leans Execution (Practiced Mastery); Terminator: Resistance 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.
Metro 2033
scarce-ammo gunfights punish sloppy aim
Terminator: Resistance
Standard FPS gunplay against machines
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
Terminator: Resistance
Terminators run fixed AI routines
Metro 2033 leans a little harder on variance, though the gap is small.
Metro 2033
hidden moral points and supplies first run
Terminator: Resistance
Some unexplored map and loot uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metro 2033
ammo-as-currency economy and stealth routing
Terminator: Resistance
Stealth routes, crafting, and skill builds are plannable
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.
