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

Execution · Practiced Mastery
Big Daddy POV return to Rapture with tighter combat systems.

Execution · Practiced Mastery
A post-apocalyptic shooter balancing stealth precision with careful resource management.
BioShock 2 leans Execution (Practiced Mastery); Metro: Last Light Redux 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.
BioShock 2
Dual-wield drill and gun timing matter.
Metro: Last Light Redux
aim and stealth timing matter
BioShock 2 leans a little harder on reads, though the gap is small.
BioShock 2
Splicer AI scripted, not adaptive.
Metro: Last Light Redux
mutants and humans are scripted
Metro: Last Light Redux leans a little harder on variance, though the gap is small.
BioShock 2
Sister-gathering waves add randomness.
Metro: Last Light Redux
resource scarcity and encounters random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
BioShock 2
Plasmid combos and gear loadouts solvable.
Metro: Last Light Redux
resource management and routing solvable
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.
