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.

Execution · Practiced Mastery
Fan-built ground-up remake of Half-Life with a reimagined Xen.

Execution · Practiced Mastery
A minimalist twin-stick shooter testing aim, movement and arena puzzle-solving.
Black Mesa leans Execution (Practiced Mastery); Thoth leans Execution (Practiced Mastery).
Thoth leans a little harder on execution, though the gap is small.
Black Mesa
Classic FPS aim and platforming sequences
Thoth
Twin-stick aiming and dodging under pressure carries each stage
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
Thoth
Enemies follow scripted geometry patterns, not adapting
Thoth leans a little harder on variance, though the gap is small.
Black Mesa
Minor enemy placement surprises first run
Thoth
Spawn timing adds bursts of chaos
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
Thoth
Solving each arena's positioning puzzle is the design
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.
