Building comparison
head to head
Black MesavsMetroid
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Black Mesa
Execution · Practiced Mastery
Fan-built ground-up remake of Half-Life with a reimagined Xen.
Metroid
Optimization · Practiced Mastery
The 1986 original that defined exploration-driven, secret-riddled platforming.
Black Mesa leans Execution (Practiced Mastery); Metroid leans Optimization (Practiced Mastery).

Axis by axis
Execution6 vs 5
Black Mesa leans a little harder on execution, though the gap is small.
Black Mesa
Classic FPS aim and platforming sequences
Metroid
stiff NES jumps and tough enemy contact
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Marines and aliens follow set scripts
Metroid
creatures follow fixed movement
Variance2 vs 3
Metroid leans a little harder on variance, though the gap is small.
Black Mesa
Minor enemy placement surprises first run
Metroid
unmarked secrets and bombable blocks hide the map
Optimization6 vs 6
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black Mesa
Route, resource, and encounter knowledge
Metroid
route and item knowledge transforms the game
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.
