head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Execution · Practiced Mastery
An open-world co-op shooter testing moderate aim and loot-driven build progression.
Metro 2033 leans Execution (Practiced Mastery); Redfall 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
Redfall
Standard FPS gunplay with forgiving co-op margins
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
Redfall
Vampires and cultists run predictable AI 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
Redfall
Loot rolls and open-world spawns add randomness
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
Redfall
Hero builds and weapon tiers form a modest progression puzzle
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.
